The 2020 Thai League Cup was the 11th season in the second era of a Thailand's knockout football competition. All rounds were played in a single-leg format. The tournament, known as the Toyota League Cup (Thai: โตโยต้า ลีกคัพ), was sponsored by Toyota. 85 clubs were accepted into the tournament, and it began with the first qualification round on 22 February 2020. The tournament has been readmitted back into Thai football after a 10-year absence. The prize money for this prestigious award was said to be around 5 million baht for the tournament winners, and 1 million baht for the second-place team.
