Russia–Turkey relations are the bilateral relations between Russia and Turkey and their antecedent states. Relations between the two are rather cyclical. From the late 16th until the early 20th centuries, relations between the Ottoman and Russian empires were normally adverse and hostile and the two powers were engaged in numerous Russo-Turkish wars, including one of the longest wars in modern history. Russia attempted to extend its influence in the Balkans and gain control of the Bosphorus at the expense of the weakening Ottoman Empire. As a result, the diplomatic history between the two powers was extremely bitter and acrimonious up to World War I. However, in the early 1920s, as a result of the Bolshevik Russian government's assistance to Turkish revolutionaries during the Turkish War of Independence, the governments' relations warmed. Relations again turned sour at the end of WWII as the Soviet government laid territorial claims and demanded other concessions from Turkey. Turkey joined NATO in 1952 and placed itself within the Western alliance against the Warsaw Pact during the Cold War, when relations between the two countries were at their lowest level. Relations began to improve the following year, when the Soviet Union renounced its territorial claims after the death of Stalin.

On 24 November 2015, a Turkish Air Force F-16 fighter jet shot down a Russian Sukhoi Su-24M attack aircraft near the Syria–Turkey border. According to Turkey, the aircraft was fired upon while in Turkish airspace because it violated the border up to a depth of 2.19 kilometres for about 17 seconds after being warned to change its heading ten times over a period of five minutes before entering the airspace. The Russia Defence Ministry denied that the aircraft ever left Syrian airspace, claiming that their satellite data showed that the Sukhoi was about 1,000 metres (1,100 yd) inside Syrian airspace when it was shot down.
