Socjaldemokracja Rzeczypospolitej Polskiej was a social-democratic (post-Commumist) political party in Poland created after the fall of Communism. The party was mostly disbanded after the formation of the SLD.

Among the creators of SdRP were current Polish president Aleksander Kwaśniewski, current speaker of the Sejm Józef Oleksy and former prime minister Leszek Miller.
