Naisten Mestis (lit. 'Women's Championship Series'; from Mestaruussarja meaning 'Championship series') is the second-highest women's ice hockey league in Finland. The league was founded as Naisten I-divisioona (Women's First Division) in 1985 by the Finnish Ice Hockey Association when the number of teams playing in the Naisten SM-sarja (now 'Naisten Liiga') was limited. It was renamed Naisten Mestis prior to the 2012-13 season.
