2016 Thai Division 1 League

2016 Thai League Division 1 (known as Yamaha League Division 1 for sponsorship reasons) was the 19th season of the League since its establishment in 1997. It is the feeder league for the Thai League T1. A total of 16 teams competed in the league this season.

Following the death of King Bhumibol Adulyadej, the Football Association of Thailand cancelled the remaining league season on 14 October 2016, with two rounds remaining.

Thai Honda were therefore crowned champions with Ubon UMT United and Port also promoted. Thai Honda and Ubon were already promoted before the announcement.

The following day however (15 October), FAT appeared to do a U-turn and announced that further discussions with key stake holders would determine whether the league campaign would continue. Although these discussions were predominantly on the back of PLT league clubs, the ruling could also effect the whole footballing structure.

On the 16 October, after a meeting of all top flight league clubs it was announced that the original decision to cancel the remaining games would stay in place, therefore crowning Thai Honda as champions.
