The Battle of Prachuap Khiri Khan (Thai: ยุทธการที่ประจวบคีรีขันธ์) was an early engagement of the Japanese invasion of Thailand in the Southeast Asian theatre of World War II. It was fought on 8–9 December 1941 at the airfield of Prachuap Khiri Khan, on the coast of the Gulf of Thailand along the Kra Isthmus. The Japanese meant to use Thailand as a base to strike at British possessions in Burma and Malaya and attacked Thailand after it failed to respond to an ultimatum sent by the Japanese government.
