The Social Democratic Party of Macedonia (Macedonian: Социјалдемократска партија на Македонија, Socijal-demokratska partija na Makedonija, SDPM) is a political party in North Macedonia.

Established in 1990,[1] the SDPM was the first political party to register in Macedonia, with Slavko Milosavlevski becoming its founding president.

It contested the 1990 parliamentary elections, at a time when Macedonia was still part of Yugoslavia.

Despite seeing its vote share fall to 1.2% in the first round of the 1994 elections, the party managed to win a single seat in the Assembly.

In the 2008 elections its vote share fell to 0.65%, as the party again failed to win a seat.
