The National Socialist Union of Finland (Finnish: Suomen Kansallissosialistinen Liitto, SKSL), later the Finnish-Socialist Party (Suomalaissosialistinen puolue) was a Finnish Nazi political party active in the 1930s, whose driving force and ideologue was Professor Yrjö Ruutu. With an ideology based on Ruutu's theories, the party came to reject orthodox German Nazism.

A minor fringe party, it received 1,406 votes in the 1933 Finnish parliamentary election.

Several prominent politicians of the right-wing faction of the post-war Social Democratic Party of Finland began their political careers in Ruutu's party.
