The Klaipėda Convention is signed formally incorporating Klaipėda Region (Memel Territory) into Lithuania.

The Klaipėda Convention was an international agreement between Lithuania and the countries of the Conference of Ambassadors signed in Paris on May 8, 1924. According to the convention, the Klaipėda Region became an autonomous region under unconditional sovereignty of Lithuania.

The Klaipėda Region or Memel Territory was defined by the 1919 Treaty of Versailles in 1920 and refers to the northernmost part of the German province of East Prussia, when, as Memelland, it was put under the administration of the Entente's Council of Ambassadors. The Memel Territory, together with other areas severed from Germany, was to remain under the control of the League of Nations until a future date, when the people of those regions would be allowed to vote on whether or not the land would return to Germany. Today, the former Memel Territory is controlled by Lithuania as part of Klaipėda and Tauragė counties.
