2017–18 Mestis season

Regular season
Top eight advance to the Mestis playoffs while the bottom two face the top two teams from Suomi-sarja for a relegation playoff. Since the highest series of Finnish hockey is a closed series no team will be promoted to Liiga.

Rules for classification: 1) Points; 2) Goal difference; 3) Goals scored; 4) Head-to-head points; 5) Penalty minutes.
