The Montreux Convention Regarding the Regime of the Straits is a 1936 agreement that gives Turkey control over the Bosporus Straits and the Dardanelles and regulates the transit of naval warships. The Convention gives Turkey full control over the Straits and guarantees the free passage of civilian vessels in peacetime. It restricts the passage of naval ships not belonging to Black Sea states. The terms of the convention have been the source of controversy over the years, most notably concerning the Soviet Union's military access to the Mediterranean Sea.

Signed on 20 July 1936 at the Montreux Palace in Switzerland, it permitted Turkey to remilitarise the Straits. It went into effect on 9 November 1936 and was registered in League of Nations Treaty Series on 11 December 1936. It is still in force today, with some amendments.

The proposed 21st century Kanal Istanbul project may constitute a possible by-pass to the Montreux Convention and force greater Turkish autonomy with respect to the passage of military ships from the Black Sea to the Sea of Marmara.

The convention was one of a series of agreements in the 19th and 20th centuries that sought to address the long-running "Straits Question" of who should control the strategically vital link between the Black Sea and Mediterranean Sea. In 1923 the Treaty of Lausanne had demilitarised the Dardanelles and opened the Straits to unrestricted civilian and military traffic, under the supervision of the International Straits Commission of the League of Nations.

By the late 1930s, the strategic situation in the Mediterranean had altered with the rise of Fascist Italy, which controlled the Greek-inhabited Dodecanese islands off the west coast of Turkey and had constructed fortifications on Rhodes, Leros and Kos. The Turks feared that Italy would seek to exploit access to the Straits to expand its power into Anatolia and the Black Sea region. There were also fears of Bulgarian rearmament. Although Turkey was not permitted to refortify the Straits, it nonetheless did so secretly.
