The Social Democratic Party of Russia (SDPR; Russian: Социал-демократическая партия России; СДПР; Sotsial-demokraticheskaya partiya Rossii, SDPR) was a political party founded in Russia by Mikhail Gorbachev on November 26, 2001.

Konstantin Titov, in turn, announced his resignation at the 3rd convention of the party held September 4, 2004.

The convention elected the new chairman, Vladimir Kishenin, leader of the Party of Social Justice, who was favoured by Titov.

When asked why he was a trusted representative for Vladimir Putin during the last presidential election,[clarification needed] Kishenin explained that this was done at the request of Vladislav Surkov, deputy director of the President's Administration.

On April 13, 2007, the party lost its official status due to its small membership.
