2023 Ykkönen

The 2023 Ykkönen was the 52nd season of Ykkönen, the second highest football league in Finland. The season began on 14 April 2023 and ended on 7 October 2023. It was the final season of the Ykkönen serving as the second-tier football league in Finland, following its demotion to third-tier.

Twelve teams contested the league. The champions (EIF) and runners-up (Gnistan) were promoted to the 2024 Veikkausliiga. The second, third, and fourth-placed teams (Gnistan, MP, and SJK Akatemia) qualified for the Veikkausliiga play-off. The bottom two teams (JJK and KPV) were relegated to the 2024 Ykkönen. The sixth-placed team (HIFK) dissolved after the season finished due to bankruptcy, giving the tenth-placed team (KäPa) a reprieve from relegation. The remaining teams were transferred to the 2024 Ykkösliiga.

The 2024 Ykkönen will represent the new third-tier level season of Finnish football.
