Thai U21 League

Season	2025
Dates	23 September 2025 – 24 December 2025
← 2024 (U23) 2026 →

The 2025 Thai U21 League, officially known as the PEA U21 Youngster League for sponsorship reasons, is the inaugural season of the Thai U21 League, under-21 football league in Thailand, organised by the Football Association of Thailand (FA Thailand) and Thai League Co., Ltd. ^[1]

The competition follows the 2024 Thai U23 League, which was preceded by FA Thailand's restructuring of its youth football system, lowering the age limit from under-23 to under-21. A total of 12 clubs compete in a single round-robin league stage, with the top four advancing to the knockout stage, which consists of semi-finals and finals. The season runs from 23 September to 24 December 2025, ^[2] with sponsorship provided by the Provincial Electricity Authority (PEA). ^[3]

Format

The competition is divided into two stages:

• League stage: Twelve teams compete in a single round-robin format, with each team playing the others once. The top four teams advance to the knockout stage.
• Knockout stage: Consists of semi-finals and a final. Both rounds are played as home-and-away two-legged ties, with the winners on aggregate advancing to the next round and the final determining the champions. ^[4]

Teams

The 2025 Thai U21 League features twelve teams representing various provinces across Thailand. The majority of these teams are concentrated in the Central, Eastern, Western, and Northeastern regions, highlighting the strong football development in these areas. This regional distribution underscores the league's commitment to nurturing football talent nationwide. ^[5]
