The 2022–23 Thai League 1 is the 26th season of the Thai League 1, the top Thai professional league for association football clubs, since its establishment in 1996, also known as Hilux Revo Thai League due to the sponsorship deal with Toyota Motor Thailand. A total of 16 teams will compete in the league. The season began on 12 August 2022 and is scheduled to conclude on 12 May 2023.[1]
The 1st transfer window is from 25 May to 9 August 2022 while the 2nd transfer window is from 19 December 2022 to 17 January 2023.
Buriram United are the defending champions, while Lamphun Warriors, Sukhothai and play-off winner Lampang have entered as the promoted teams from the 2021–22 Thai League 2.
Promoted from the 2021–22 Thai League 2
Relegated from the 2021–22 Thai League 1
There are 16 clubs in the league, with three promoted teams from Thai League 2 replacing the three teams that were relegated from the 2021-22 season.
Samut Prakan City, Suphanburi and Chiangmai United were relegated at the end of the 2021–22 season after finishing in the bottom three places of the table. Chiangmai United made their immediate return to the second-tier, while Suphanburi ended a 9-year stint in the top-flight. Samut Prakan City, on the other hand, experienced their first-ever relegation as their current incarnation, having last experienced the drop back in 2013 when they were still known as Pattaya United. The three were replaced by 2021-22 Thai League 2 champions Lamphun Warriors, who are making their maiden appearance in the top flight. They were joined by runners-up Sukhothai, who made their immediate return to the top flight and Lampang, the promotion playoff winner which was first held in 2020–21 season. Like Lamphun, Lampang are making their top-flight debut this season.
