The Thailand Champions Cup is a single-game competition between the winners of previous Thai League 1 and Thai FA Cup, organised by the Football Association of Thailand. If the Thai League 1 champions also won the FA Cup, then the league runners-up provide the opposition. The first edition started in 2017 in order to replace the Kor Royal Cup.

The Thai League 1, often referred to as T1, is the highest level of the Thai football league system. Contested by 16 clubs, it operates on a system of promotion and relegation with Thai League 2. Seasons typically run from August to May, with each team playing 30 games: two against each other team, one home and one away. It is sponsored by Toyota Motor Thailand and therefore officially known as the Hilux Revo Thai League. In the Thai League, most games are played on Saturday and Sunday evenings, with occasionally played on Wednesday and Friday evening fixtures.
