The Thailand national under-23 football team (Thai: ฟุตบอลทีมชาติไทยรุ่นอายุไม่เกิน 23 ปี, RTGS: futbon thim chat thai run ayu mai koen yi-sip-sam pi), also known as the Thailand Olympic football team, is the national team for the under-23 and 22 level, representing Thailand in international football competitions in the Olympic Games, Asian Games and Southeast Asian Games, as well as any other under-23 international football tournaments including the AFC U-23 Championship. It is controlled by the Football Association of Thailand.

The team has won the Southeast Asian Games gold medal for a record seven times, making it the most successful among ASEAN football teams. Despite its major domination in Southeast Asia, the team never won any gold medal in Asian level.
