2025–26 Thai League 1

The 2025–26 Thai League 1 will be the 9th season of Thai League 1 under its current name and the 29th season of top-flight Thai football professional league since its establishment in 1996. This league also known as BYD Sealion 6 League I due to the sponsorship deal with BYD Auto. The season is scheduled to begin on 15 August 2025 and will conclude on 10 May 2026.

Buriram United entered the season as the four-time defending champions, having won their 4th consecutive league title and 11th overall Thai top-flight football title in the previous season.^[1]

16 teams will compete in the league – the thirteen teams from previous season and three teams promoted from Thai League 2.

Chonburi and Ayutthaya United became the first two teams to be promoted on 26 April 2025 after winning their respective matches. Chonburi were also crowned champions by defeating Suphanburi 0–1 in an away match, while Ayutthaya United beat Bangkok 5–1. Kanchanaburi Power became the last team to be promoted after their win against Phrae United 4–5 on aggregate in promotion play-off match.

Chonburi returned to the top division after a one-season absence, while for Ayutthaya United and Kanchanaburi Power this was their first season in the top division in their history, respectively.^[2]

Khonkaen United became the first team to be relegated on 30 March 2025 after suffering a 0–5 defeat to Bangkok United. The result ended their time in the top division for 4 seasons.^[3]

Nakhon Pathom United became the second team to be relegated on 13 April 2025 after earning a 2–2 draw against Port. The result ended their time in the top division for 2 seasons.^[4]

Nongbua Pitchaya became the third and final team to be relegated after suffering a 1–2 defeat to Port and Rayong's win over Khonkaen United on 20 April 2025. These results meant that Nongbua Pitchaya only lasted one season in the top division and returned to the second division.^[5]

^3 Capped for Thailand.

The table lists the positions of teams after each week of matches. In order to preserve chronological evolvements, any postponed matches are not included in the round at which they were originally scheduled, but added to the full round they were played immediately afterwards. For example, if a match is scheduled for matchday 13, but then postponed and played between days 16 and 17, it will be added to the standings for day 16.
