2025–26 Thai League 3 Central Region

The 2025–26 Thai League 3 Central Region is part of the 2025–26 Thai League 3 Regional Stage,^[1] consisting of 11 clubs located in the central region of Thailand. The season will commence on 13 September 2025, with clubs competing in a round-robin format featuring home-and-away matches. The Regional Stage will conclude on TBD, at which point the top two clubs will advance to the National Championship Stage, while the bottom-placed club will face relegation to the Thailand Semi-pro League for the following season. This stage highlights the vibrancy of central Thailand, where clubs compete within a diverse and dynamic landscape, reflecting the region's strategic importance in the country.

The 2025–26 Thai League 3 season features a number of changes compared to the previous campaign. These include the promotion and relegation of clubs between divisions, several club renamings and rebrandings, and the introduction of a new title sponsor, BYD Auto, which rebranded the competition as the BYD Dolphin League III for sponsorship reasons.

Normally, the champions of each of the six regional groups of the 2025 Thailand Semi-pro League would be promoted to the Thai League 3.^[2] However, in the Western region, the champions, The Wall, failed club licensing and were denied promotion. As a result, only five regional champions earned direct promotion, with several additional clubs promoted under special quotas due to licensing issues and adjustments to balance the number of teams in each group. Clubs promotion in the Central region:

• Singburi Warriors – promoted as regional champions.
• Futera United – admitted as third-placed team, after both AUU Inter Bangkok and Dome (Thai League 3 survivors) failed licensing, and runners-up Ayutthaya PK also failed licensing.^[3]

In addition to the regular relegations, two clubs were demoted from the Thai League 3 Central region after failing to obtain a club licensing certificate for the 2025–26 season.

• AUU Inter Bangkok – failed licensing and were removed from the league.
• Dome – failed licensing; as a consequence, Saraburi United, who finished bottom of the Central region table, retained their place in Thai League 3.

As a result, the lowest-placed side, Saraburi United, was spared relegation.

In the 2025–26 season, Thai League 3 will operate under a title sponsorship arrangement for the first time: BYD Auto (through BYD Rêver Thailand) has become the main sponsor for all three professional tiers in Thailand, including Thai League 3, rebranding it as the BYD Dolphin League III.^[4]

On the broadcasting side, a landmark media rights deal was struck, giving AIS Play (in partnership with Gulf and JAS)^[5] exclusive rights to stream all matches from Thai Leagues 1, 2, and 3, plus domestic cups and youth competitions for the 2025–26 through 2028–29 seasons.^[6] Under this agreement, Thai League 3 matches can be watched live for free via AIS Play, and fans will no longer rely solely on individual clubs' streaming efforts (e.g., via YouTube or Facebook), as they did in previous seasons.

2 clubs have changed their logos for the 2025–26 season of the Thai League 3 Central region:

• Royal Thai Air Force, introduced a completely new crest. The previous emblem, which closely resembled the insignia of the Royal Thai Air Force with golden wings, a star, a tricolour shield, and a radiant crown, was replaced by a minimalist and modern design featuring geometric shapes representing wings and a star, with the club's name in Thai "ทหารอากาศ เอฟซี" displayed below.
• Singburi Warriors, a newly promoted club, unveiled a redesigned crest upon their promotion from the Thailand Semi-pro League. The previous emblem featured two red Singha lions facing each other with a football at the center, while the new design simplifies the imagery to a single silver Singha lion alongside a football, set against a two-tone maroon and gold shield with the club's name in a stylized font.

The distances between football clubs in the 2025–26 Thai League 3 Central Region are approximate and calculated using the most convenient, shortest practical road routes. These routes emphasize travel efficiency and accessibility, avoiding unnecessarily indirect paths even when marginally shorter alternatives exist. The figures, therefore, represent realistic road journeys that clubs are expected to undertake for away matches within central Thailand. This overview highlights the logistical challenges faced by teams and provides a useful reference for travel and operational planning during the season.

Among the distances calculated, the shortest is 12 kilometers, representing the trip between North Bangkok University and Royal Thai Air Force. Conversely, the longest road journey spans 148 kilometers, marking the trip between Kasem Bundit University and Lopburi City. In terms of total seasonal travel, Singburi Warriors face the most extensive travel, covering approximately 988 kilometers, while Royal Thai Air Force has the least, with a total of about 549 kilometers. These travel disparities are presented in the accompanying table, which offers a detailed breakdown of road distances between each club and provides valuable insights into the logistical demands that clubs face in the 2025–26 season.
