The Japan–Korea Treaty of 1910, also known as the Japan–Korea Annexation Treaty, was made by representatives of the Empire of Japan and the Korean Empire on August 22, 1910. In this treaty, Japan formally annexed Korea following the Japan–Korea Treaty of 1905 by which Korea became a protectorate of Japan and Japan–Korea Treaty of 1907 by which Korea was deprived of the administration of internal affairs.

Japanese commentators predicted that Koreans would easily assimilate into the Japanese Empire.In 1965, the Treaty of Basic Relations between South Korea and Japan confirmed this treaty is "already null and void".
