The Thai FA Cup (Thai: ไทยเอฟเอคัพ), known officially as The Football Association of Thailand Cup, is a football cup competition in Thailand. Thai FA Cup is an annual knockout association football competition in men's domestic football. It was held between 1980 and 2001 and relaunched in 2009. Bangkok Bank won the first two editions.
In 2009 it was announced that the Thai FA Cup would return to the Thai football calendar. All the teams from the Thai League 1 and Division 1 League were automatically entered and teams from the Division 2 League as well as university and schools teams could apply to enter. The qualifying round took place from 27–30 June. The first round proper will see sixteen qualifiers progress to the second round where they will each meet a Division 1 side. The sixteen TPL teams enter at the third round stage. The final will be played at National Stadium with the winning team receiving 1,000,000 Thai baht. The runners-up will receive 500,000 Thai baht.
The competition proceeds as a knockout tournament throughout, consisting of five rounds, a semi-final and then a final. There is no seeding, the fixtures in each round being determined by a random draw. Prior to the semi-finals, fixtures ending in a tie are extra time have been decided by penalty shoot-out. The first rounds are qualifiers, with the draws organised on a regional basis. The next rounds are the "proper" rounds where all clubs are in one draw.
