← 2024–25 2026–27 → | |
The 2025–26 Thai League 3 Western Region is part of the 2025–26 Thai League 3 Regional Stage,[1] consisting of 11 clubs located in the western region of Thailand, along with some from the western part of the central region. 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 brings together clubs from the lush landscapes and mountainous terrain of the West, where football continues to unite communities in a region of natural beauty.
Seasonal Changes
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.
Relegation from Thai League 2
Originally, three clubs were scheduled to be relegated from the 2024–25 Thai League 2 to the Thai League 3. However, during the 2024–25 season, Samut Prakan City withdrew and dissolved, leading to the annulment of all their league results. As a result, only two clubs were set to be relegated.
At the end of the season, Lampang, who had secured survival in Thai League 2, failed to obtain a license to participate in the 2025–26 season and was therefore demoted to the amateur level. Their place in Thai League 2 was retained by Pattaya United, who had originally been among the relegated clubs. Consequently, only one club was relegated to Thai League 3: Suphanburi, who finished bottom of the Thai League 2 standings. Suphanburi have been placed in the Western region of Thai League 3, in line with the location of their home ground in Western Thailand.
Promotions from Thailand Semi-pro League
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.
Club relegated due to club licensing failures
In addition to the regular relegations, one club was demoted from the Thai League 3 Western region after failing to obtain a club licensing certificate for the 2025–26 season.
- Maraleina – failed licensing and were relegated to the lower divisions.
Club relegated due to finishing last in the region
Alongside the licensing-related relegations, one club was demoted from the Thai League 3 Western region after finishing at the bottom of the respective regional leagues in the 2024–25 season.
- Kanchanaburi City – finished last in the Western region and were relegated.
Sponsorship and Broadcasting
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.[3]
On the broadcasting side, a landmark media rights deal was struck, giving AIS Play (in partnership with Gulf and JAS)[4] 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.[5] 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.
Club logo changes
2 clubs have changed their logos for the 2025–26 season of the Thai League 3 Western region:
- Samut Sakhon City, updated their crest ahead of the 2025–26 season. The previous circular logo, which featured a photographic tiger head within a blue border, was replaced with a shield-shaped design that retains the tiger motif but incorporates additional maritime elements, including an anchor and a ship's wheel, along with the inscription Since 2022.[6]
- Samut Songkhram City, updated their crest ahead of the 2025–26 season. The previous version featured a red shield with a stylized stingray motif and the inscriptions "SSC 2021". The revised crest retained the red shield and stingray motif but adopted a more dimensional appearance and replaced the inscriptions with "Samut Songkhram City".

Stadiums and locations
Road travel distances between clubs
The distances between football clubs in the 2025–26 Thai League 3 Western Region are approximate and calculated using the shortest practical and most accessible road routes. These measurements favour travel paths that balance proximity with convenience, avoiding indirect or impractical alternatives despite marginal differences in distance. By focusing on realistic road networks across western Thailand, the chart reflects the actual journeys clubs will undertake for away fixtures and provides essential insight into the logistical demands faced throughout the season.
Among the calculated distances, the shortest is 0 kilometres, representing Nonthaburi United and Rajpracha, who share the same home stadium and therefore require no travel between them. In contrast, the longest road journey spans 292 kilometres, marking the trip between Hua Hin City and Suphanburi. Regarding cumulative travel distance across the season, Hua Hin City records the highest total at approximately 1,949 kilometres, reflecting the significant travel burden it faces. Meanwhile, Royal Thai Army registers the lowest total travel distance at around 562 kilometres. These disparities are outlined in the accompanying table, providing a detailed breakdown of inter-club road distances and illustrating the varied logistical challenges within the 2025–26 campaign.
