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.[2]
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.[3]
Yangpyeong FC, FC Namdong and Chungju Citizen forfeited three, seven and twelve matches respectively due to their use of illegal players.[4] Additionally, FC Namdong forfeited seven more matches by being disbanded in the middle of the season.[5]
Goyang KH qualified for the K3 League as champions, but they were disbanded after the end of the season.[6]
