The 2026 Thailand Semi-pro League is the fourth season of the Thailand Semi-pro League, serving as the official fourth tier of the Thai football league system. The league is organized by the Football Association of Thailand (FA Thailand) and managed by Thai League Co., Ltd.
A total of 53 clubs compete in the season, with each club required to meet the Semi-pro Club Licensing requirements. Admission is based on an application process conducted by the league organizers. The season began on 18 April 2026 and concluded on 7 June 2026 with the second leg of the Finals, where the national champion was crowned.
The competition consists of a Regional Stage followed by the Finals. The champions of the six regional zones earn automatic promotion to Thai League 3 for the following season. Following the conclusion of the Regional Stage, the six regional champions are ranked in accordance with the competition regulations, with the two highest-ranked clubs qualifying for the Finals.
A notable change for the 2026 season was the introduction of a league-phase scheduling system in the Regional Stage. Under this format, match fixtures are pre-generated through a computerized draw before clubs are assigned to their respective positions. Each club plays six matches, consisting of three home matches and three away matches, ensuring that all clubs play the same number of matches regardless of the number of participating clubs in each region.

Regional stage The league continues to be divided into six regional zones, following the structure of Thai League 3. The number of participating clubs in each region varies according to club licensing approval; however, the competition format is standardized across all regions for the 2026 season. In the Regional Stage, a league-phase format is used. Match pairings are predetermined through a computerized draw, with each position assigned a fixed schedule of opponents comprising three home matches and three away matches. Clubs are subsequently drawn into these positions, which determine their fixture schedule for the season. Each club plays a total of six matches. Unlike previous seasons, all regions follow the same competition format, ensuring that every club plays the same number of matches regardless of the number of participating clubs in its region. At the conclusion of the Regional Stage, the top-ranked club in each region is crowned regional champion and earns promotion to Thai League 3 for the following season. The six regional champions are then ranked according to the competition regulations based on their Regional Stage records, with the two highest-ranked clubs qualifying for the Finals to compete for the national championship.
