The 2023 Thailand Semi-pro League is the first season of the Thailand Semi-pro League, the fourth-tier professional league for association football clubs in Thailand, since its establishment in 2023, also known as PTT Lubricants Semi-pro League due to the sponsorship deal with PTT Lubricants. A total of 34 teams would be divided into 5 regions including 5 teams in the Northern region, 10 teams in the Northeastern region, 7 teams in the Eastern region, 5 teams in the Western region, and 7 teams in the Bangkok metropolitan region.
Note:
- ↑ Due to the promotion of Chanthaburi and Pattaya Dolphins United in the 2022–23 Thai League 3 Eastern region, there must be 2 teams in the 2023 Thailand Semi-pro League Eastern region promoted to replace them.
- ↑ Because there is no competition in the Southern region of the 2023 Thailand Semi-pro League, the right to promotion goes to the winner of the 2023 Thailand Amateur League Southern region.
