True Bangkok United Football Club is a professional football club based in Pathum Thani province, Thailand. Known as Bangkok University Football Club until 2009, the club was relegated from the 2010 Thai Premier League only four years after winning their first league title in 2006. In 2012 they were promoted to Thai League 1, after finishing third in the 2012 Thai Division 1 League.

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.
