The Battle of Prachuap Khri 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.^[1] The Japanese meant to use Thailand as a base to strike at British possessions in Burma and Malaya and attacked Thailand without warning.

The last Thai veteran to have fought in this battle, Choi Lodthanong, died on 2 June 2021 at the age of 100.^[2]^[3]
