2022 K4 League

The 2022 K4 League was the third season of the K4 League.

Defending champions Pocheon Citizen were promoted to the K3 League alongside runners-up Siheung Citizen and play-off winners Dangjin Citizen, while Pyeongtaek Citizen played in the K4 League for the first time by being relegated from the K3 League. Three K League clubs Daegu FC, Daejeon Hana Citizen and Jeonbuk Hyundai Motors joined the K4 League, and entered with their reserve teams.

The 17 participating teams played each other twice during the regular season. The top two teams could be directly promoted to the K3 League, and the third and fourth-placed teams qualified for the promotion play-offs.

Yangpyeong FC, FC Namdong and Chungju Citizen forfeited three, seven and twelve matches respectively due to their use of illegal players. Additionally, FC Namdong forfeited seven more matches by being disbanded in the middle of the season.

Goyang KH qualified for the K3 League as champions, but they were disbanded after the end of the season.
