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 2021âÂÂ22 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 2020âÂÂ21 season. Like Lamphun, Lampang are making their top-flight debut this season.
