The Popular Social Party (Greek: Λαϊκό Κοινωνικό Κόμμα) was a Greek political party that formed after a split from the People's Party.
It was founded in January 1956 by Stefanos Stefanopoulos.
The Popular Social Party participated in the elections of 1956 but failed to enter the parliament.
Its main political program, as it was claimed, was social and economic justice.
The party suggested social reforms and a new organization of the Greek economy.
