Mestis (from 'Mestaruussarja', 'Championship series'), is the second-highest ice hockey league in Finland.
The league was established in 2000 to replace the I-Divisioona. Since 2000, Mestis has been the highest hockey league in Finland that can be reached with playing merits only; the SM-liiga was closed (to teams being relegated or promoted) in 2000. After the 2004–05 season, KalPa was promoted to the SM-liiga, and the league was re-opened in the 2008–09 season.
