The Movement for Social Democracy (Greek: Kinima Sosialdimokraton) is a political party in Cyprus. It is led by Yiannakis Omirou .

In the 2001 general elections it took 4 of 59 seats in the House of Representatives of Cyprus . It is a member of the Party of European Socialists.

The party was founded by doctor Vasos Lyssaridis in 1970 with the name EDEK. Members were drawn from the committee for re-establishment of democracy in Greece, and fighters from Lyssaridis's group during the 1964 clashes between Greek and Turkish Cypriots. The party supported president Makarios III and a lot of its members were part of the armed resistance to the 15th July 1974 coup against him. The leader of the youth section of the party, Doros Loizou, was shot and killed in an attempt to murder Lyssaridis himself in August 1974.

Several members of the party's youth section (EDEN) with trotskyist tendencies were expelled between 1979-1984 and formed Aristeri Pteryga (Left Wing).
