The 2025 K3 League is the sixth season of the semi-professional K3 League. It is the third tier of men's football in South Korea.
The pre-season winter transfer window opened on 1 January 2025 and will close on 24 March 2025. The summer transfer window will open on 20 June 2025 and close on 31 July 2025.[ citation needed ]
On 11 August 2025, Gimhae FC and Paju Citizen were approved to join K League 2 from the 2026 season after switching to a professional team in the 4th meeting of the K League Board, this is the last play in the third tier.
The regular season will be played over 30 rounds (28 rounds), beginning on 1 March 2025. [1] [2] Due to the odd number of teams following Hwaseong FC's move to K League 2, each round will have one team on a bye. [2] The winner of the regular league will be crowned as champions without a playoff, and the 15th-placed team will be automatically relegated to the K4 League. The 14th-placed team will play in a promotion-relegation playoff against the 2nd-placed team in the 2025 K4 League. [3]
On 8 September 2025, the 2025 K3-K4 promotion-relegation system was changed and the lowest ranked team in the K3 League will advance to the K3-K4 League promotion/relegation playoffs instead of being automatically relegated.
Fifteen teams will compete in the 2025 season. Teams must include at least three U-23 players in their matchday squad, and at least one of those players must be in the starting line-up. Teams are limited to four players of foreign nationality. [3]
