I-Divisioona was the second tier of ice hockey in Finland from 1974 to 2000. It replaced the previous league Suomensarja that ran from 1936 to 1974.
I-Divisioona was known as the Finland-liiga (1992–1994) and the Fazer liiga (1994–1996) due to naming rights deals.
In 2000, I-Divisioona was replaced by Mestis.
