The 2025–26 Thai League 3 Cup is the 3rd season of a Thailand's knockout football competition. Matches are organized into two phases: the league and the knockout phases. In the league phase, clubs compete in a regionally based format with a fixed number of matches per club, while the knockout phase follows a single-elimination structure. The competition retains its sponsorship by BG Container Glass (BGC) and Muang Thai Insurance (MTI), and it is officially named the BGC Muang Thai Insurance Cup (). A total of 53 clubs from the 2025–26 Thai League 3 are participating. The tournament commenced on 29 November 2025 and concluded with the final on 28 March 2026. The prize pool remains unchanged, with the champions awarded 3 million baht and the runners-up receiving 1 million baht.

League phase In the league phase, the 53 participating clubs are divided into six regions based on the 2025–26 Thai League 3 regional divisions. Unlike a traditional round-robin system, each club plays four matches (two at home and two away) against opponents randomly drawn by a computerized system within their region. Standings are maintained separately for each region. At the end of the league phase, the top two clubs from each region automatically qualify for the knockout phase. Additionally, the third-placed clubs from all six regions are ranked against each other, with the four best-performing clubs earning the remaining slots in the knockout phase.

Knockout phase The knockout phase consists of 16 clubs: the 12 automatic qualifiers from the league phase and the four best third-placed clubs. The phase adopts a single-elimination format, starting from the Round of 16, followed by the quarter-finals, semi-finals, and the final. All matches in the knockout phase are single-legged except for the semi-finals, which are played over two legs. In the event of a tie in the semi-finals, the away goals rule applies, followed by penalty shootouts if necessary. The final is played as a single-leg match to determine the tournament champion.
