Left Socialists (Danish: Venstresocialisterne) was a political party in Denmark. The party worked on what it called an 'undogmatic revolutionary and Marxist basis'.
In 1989 the Left Socialists founded the Red-Green Alliance with the Communist Party of Denmark and Socialist Workers Party to contest in elections. At its last congress in 1998 the Left Socialists transformed itself from a party to an association. Since then, VS concentrates most of its work towards building of the Red-Green Alliance. It still publishes Solidaritet (Solidarity) and maintains a website, but except for that it has little activity of its own.
