2016–17 Mestis season

The 2016–17 Mestis season was the 17th season of Mestis, the second highest level of ice hockey in Finland after Liiga. Previous season's champion Jukurit got a place in the Liiga. IPK got promoted from Suomi-sarja at the end of last season. Espoo United got a place in Mestis after Espoo Blues suffered bankruptcy and the league was exceptionally played with 13 teams.
At the end of the season SaPKo won both the regular season and the playoffs. Hokki and IPK retained their place in Mestis, while JYP-Akatemia was relegated. Hokki faced bankruptcy during the off-season and thus Imatran Ketterä were awarded a place in Mestis for the next season.
