The 2018 Thai League Cup is the 9th season in the second era of a Thailand's knockout football competition. All games are played as a single match. It was sponsored by Toyota, and known as the Toyota League Cup (Thai: โตโยต้า ลีกคัพ) for sponsorship purposes. 82 clubs were accepted into the tournament, and it began with the first qualification round on 28 February 2018, and concluded with the final on 20 October 2018. The tournament has been readmitted back into Thai football after a 10-year absence. The prize money for this prestigious award is said to be around 5 million baht and the runners-up will be netting 1 million baht.
The prize money is not the only benefit of this cup, the team winning the fair play spot will get a Hilux Vigo. The MVP of the competition will get a Toyota Camry Hybrid Car. The winner would have qualified for the 2018 Mekong Club Championship final and the 2019 Toyota Premier Cup.
This is the first edition of the competition and the qualifying round will be played in regions featuring clubs from the Thai League 3 and Thai League 4.
