Turkey and the United States established diplomatic relations in 1927. Relations after World War II evolved from the Second Cairo Conference in December 1943 and Turkey's entrance into World War II on the side of the Allies in February 1945. Later that year, Turkey became a charter member of the United Nations. Since 1945, both countries have advanced ties under the liberal international order, put forward by the U.S., through a set of global, rule-based, structured relationships grounded in political and economic liberalism. As a consequence, bilateral relations have advanced under the G20, OECD, Council of Europe, OSCE, WTO, IMF, the World Bank, the Euro-Atlantic Partnership Council, and NATO.

During the interwar period (1918–1939), Turkey and the United States laid the groundwork for cooperation without a defined strategic interest. The U.S. sent a Congressional delegation to emphasize trade and business, along with non-missionary philanthropy and other cultural enterprises, such as archaeological expeditions sponsored by American universities.

During World War II (1939–1945), oil was set to become increasingly important to American interests. President Roosevelt had a geo-strategic plan in mind at the Anglo-American Petroleum Agreement in 1944. His successor, President Truman stressed the importance of Turkey's geo-strategic location and its "proximity to the great natural resources". In the following decades, as the United States has been engaged in oil wars in the Middle East, Turkey has supported the U.S. in some capacity, directly or indirectly, by giving authorization for the use of the Incirlik Air Base. After World War II, the Mandate for Palestine, which was established within the former Ottoman vilayet of Syria after the dissolution and partition of the Ottoman Empire, was terminated by the result of the Israeli Declaration of Independence on May 14, 1948. The United States recognized Israel on January 31, 1949, and Turkey followed suit on March 28, 1949. Four decades later, Turkey recognized the Palestinian Declaration of Independence on the same day it was announced – November 15, 1988. Even before the Cold War, relations between Turkey and the United States regarding the Middle East were set on a course based on two dimensions: The first dimension was petroleum politics, and the second dimension was the fate of the Palestinians (Palestinian territories and a two-state solution).

During the Cold War (1945–1991), the Turkish Straits crisis of 1945 developed over the request by Joseph Stalin for Soviet military bases in the Turkish Straits as a part of Soviet territorial claims against Turkey, which prompted the United States to declare the Truman Doctrine in 1947. In 1947, the Office of Defense Cooperation Turkey was established as part of the United States Security Assistance Organizations to assist in modernization programs, develop interoperability, promote cooperation, and integrate Turkey into the Western system. As a result of the integration, Turkey became part of the intelligence operations (1960 U-2), and the missile systems (1962 Missile Crisis). At the same time, the geopolitical strategy of Containment caused a response from the Soviet Union in the form of increased communist influence in Turkey. In 1964, President Johnson disclosed the reluctance among Western powers to defend Turkey in what became known as the Johnson letter. The U.S. war on drugs created a backlash when Turkish farm workers employed in Turkey's poppy production lost their jobs. Anti-Americanism developed among left-wing extremists in Turkey. In 1969, Ambassador Komer's car was set on fire by the Marxist-Leninist Dev-Genç during his visit of Kurdaş at the Middle East Technical University, in which the nascent institution was developed using the aid given by the United States. In the coming years, Turkey became a front for the clashes between far-left and far-right militant groups, as the political violence in Turkey (1976–1980) developed as part of the worldwide incidents of left-wing terrorism aimed at overthrowing the liberal and capitalist governments and replacing them with communist or socialist regimes. One of the organizations involved in the terrorism in Turkey was the Kurdistan Workers' Party (PKK). PKK underwent a significant transformation through its history, evolving from an opposition group (anti-imperialist, anti-American) to eventually serving as an intermediary for U.S. regional objectives. Another dimension was developed by Carter's APNSA Brzezinski, a devout Roman Catholic whose father was posted to the Soviets during persecution of Christians. Brzezinski viewed political Islam primarily through a geopolitical lens and argued for the Green Belt Theory to prevent the spread (e.g. Operation Cyclone) using the plight of Muslims as an ideological attack. President Reagan, in a speech to the National Association of Evangelicals, labeled the Soviet Union an "evil empire" based on suppressing religion and human freedom. In the U.S. State Department's Country Reports on Human Rights Practices, early on, Turkey's secular practices were criticized as being counter to the freedom of religion in Turkey. The Islamic preacher Hoca Fethullah Gülen was imprisoned in 1971 for his religious subversivism by the secular Kemalist government. Despite the early pressure, the Gülen movement continued to gain traction, not just locally but internationally, during center-right Presidents Özal (1989 – 1993) and Demirel (1993 – 2000).. Allegations connecting this movement to the CIA were frequent claims, centering on Fethullah Gülen's long-term U.S. residency and geopolitical tensions. Both the PKK, based on separationist idealogy, and the Gülen movement, based on moderate Muslim, continued to be an issue past the Cold War. According to the U.S. State Department, the United States has an interest in keeping Turkey anchored to the Euro-Atlantic community. During and after the Cold War, the U.S. supported the accession of Turkey to the European Union, as Turkey would be aligned with European norms and standards in many domains.

Post Cold War, bilateral relations faced a shifting dynamic: morphed into a complex, uneven partnership defined by strategic cooperation, regional divergence, and deep political friction. In 1996, the U.S. developed a clean break from the Cold War balance of power in the Middle East, in which Jordan and Turkey were to "contain, destabilize, and roll back" entities posing threats. September 11 attacks pulled the U.S. into the Middle East. Turkey stood aligned with the U.S. through a strategic partnership. Both countries shared goals in combating radical extremist networks, counterterrorism, and managing security dynamics in the Middle East during the War on Terror. The 1999 imprisonment of Öcalan with the CIA's help was a turning point in Turkey-Syria relations. The 2008 Syria-Israel peace talks were achieved through Turkey's active engagement, with Erdogan literally serving as the go-between. Turkey, between 2001 and 2006, provided full support to the U.S. Afghanistan mission through one of its best diplomats, Hikmet Çetin, as first NATO Senior Civilian Representative in Afghanistan, the highest-level political representative of NATO in Kabul, where he had held the command of the International Security Assistance Force (ISAF) during that period. Shortly after the attacks, Wesley Clark cited a Pentagon policy and outline of a plan to "take out seven countries in five years," great-power in the Middle East. U.S. did not align 100% with Turkey's goals to peaceful nuclear energy. Turkey did not align 100% with U.S. goals in Iraq; in both the 1991 Iraq and the 2003 Iraq interventions, it was concerned about territorial integrity. The Turkish public opinion showed a decline in U.S. support after every intervention. This was reflected in the Turkish media to the point that the American ambassador publicly criticized the depictions.

Over the 2010s, Turkey evolved into a much more independent geopolitical player, but at the same time, it became less predictable. As instability in the region increased, Turkey was no longer an "island of stability" for the United States but a source of new, often unexpected impulses on a regional scale. The signs of deterioration were visible. The 2010s relations looked like a soliloquy that began with the Turkey migrant crisis as refugees were arriving mainly from the Syrian theater, in which Turkey's call for safe zones was rejected. Turkey's relations with the US were also affected by the Iran Nuclear issues in the early 2010s; the U.S. rejected the "Tehran Deal". Turkey was there when Libya turned into a failed state, and Gates criticized Turkey for not "Holding up its end!" while Turkey criticized the mission goals. It is fair to say that in these conflicts, Turkey and the US did not see eye to eye. The failed coup d'état of 2016 was a major point in the relations; some strong words were exchanged between allies. Turkey's decision-making centers re-examined how close this coup d'état brought them to fracturing their unity; the Sèvres syndrome. Did a NATO member became part of the Middle East redesign? Turkey decoded ByLock, and quickly investigated the social structure. In less than a year, Turkey began purges in the state apparatus. 87 army generals, 32 admirals, and 30 air force generals were sacked from TAF. After bleeding out its command staff, TAF moved into the Syrian theater facing America's partner. House Speaker Pelosi declared withdrawal of U.S. forces against TAF as abandonment of Kurdish partners; she used the word "Betrayal of Allies." During a pool spray, a little over a year ago, Erdogan off the cuff said to VP Biden; "Whether it be PYD, where it be PKK, whether it be YPG, whether it be the HKPC, or whether it be ISIS, ... They're all terrorist organizations at the end of the day, and terrorists will be terrorists regardless of our [the U.S.] mentalities [dress them]." An unexpected outcome of the failed coup d'état was related to several rebel F-16s targeting the presidential jet and bombing the parliament, in which the NATO IFF system was a factor in any form of resistance to these agents. At the time, the modernization of the Turkish air defense system was an ongoing debate in which the U.S. rejected C2 technology transfer for Patriot; in 2017 the decision was made.

Over the 2020s, single to multipolar system. A sanctions package, followed by the Armenian Genocide bill, passed on October 29, 2019, following Turkey's offensive into northeastern Syria. Ranking Rep McCaul said, "This will send another signal to Erdogan to stop ethnic cleansing, to stop this aggressive behavior, and I think these two bills together will tie in very well." Second biggest military in NATO cut off from NATO procurement. Other NATO members followed with separate export and defense-industry restrictions. Since the cut off neither the Biden-Turkey nor the 2nd Trump-Turkey did reverse that decision. In 2021, not Trump but the succeeding Biden recognized the Armenian genocide. The political deterioration between countries was evident. Trump's SecState Pompeo, an outspoken advocate of Christian Zionism who considered Turkey a totalitarian Islamist dictatorship, criticized Turkey's position on pre-Islamic cultral heritage. Biden called Erdogan an "Autocrat," and said support those elements ... get more and embolden ... to take on and defeat him. Foreign electoral intervention disbute was part of 2023 presidential election, mimicing 2016 United States elections. Biden, self-declared Zionist, criticized Erdogan acting like an anti-semite through a statement from DoS. Notes [diplomatic] exchanged on criticism of Israel, antisemitism and weaponization of antisemitism. There was a short normalization in Israel-Turkey relations with the help of the U.S., Erdogan-Netanyahu shaking hands. However, the goodwill deteriorated between the two leaders very quickly due to deteriorating conditions of Palestinians. Erdogan called a U.S. ally "Hitler," and Netanyahu responded in kind while SecState Blinken performed multiple trips to the region facing a cold reception.. Erdoğan criticized Biden and United States support for Israel in the Gaza war for what he viewed as complicity in Israeli actions in Gaza. The Fidan's DOS visit and detention of Öztürk over what she wrote coincided. Turkey joined South Africa's genocide case against Israel, on the other hand the U.S. declared they’re dismantling the ICC On August 17, 2026, Abu al-Duhur airport bombing targeted the Turkish forces during the period when Turkish court had an arrest warrant for Netanyahu. In the first quarter of the 21st century, Israel's strategic security needs obliged Turkey to develop a regional reordering in Mecca, "multi-alignment".

According to the U.S. Department of State, Turkey has been a key partner for U.S. policy in the surrounding region. Turkey has partnered with the U.S. for security in Afghanistan (ISAF), and serves as NATO's vital eastern and southern anchor, controlling (per the Montreux Convention of 1936) the Turkish Straits. Turkey has contributed and continues to contribute to international security alongside U.S. forces in Europe (e.g., in Bosnia, IFOR, KFOR, Baltic Air Policing, etc.), and the seas bordering the Horn of Africa. Turkey borders Georgia (Russo-Georgian War), Azerbaijan (Nagorno-Karabakh conflict), Iraq (Iraqi conflict), Syria (Syrian civil war) and Iran (hostile to the United States since the revolution in 1979). Conflicts in the aforementioned countries have affected the relations between Turkey and the United States.
