Russian Socialist Party (RSP; Russian: Русская социалистическая партия, romanized: Russkaya sotsialisticheskaya partiya) was a political party in Russia led by Vladimir Bryntsalov.

Despite the leftist-sounding name, the main priorities of the activities indicated in the party's program were the ideas of moderate conservatism, traditionalism, and social orientation.^[2] Other value guidelines were most fully presented in other RSP program documents, however, they were not actually translated into practical activities.

The RSP was formed at a Founding Congress on 27 April 1996. Like many other electoral associations of that period, in the second half of the 1990s, the party developed a new version of amendments and additions to its Charter, which was associated with obtaining the status of a political public association.^[3] The Russian Socialist Party was registered by the Ministry of Justice of the Russian Federation on 7 December 1998. The chairman of the party during its existence was Vladimir Bryntsalov. In the 1999 Russian legislative election, the Russian Socialist Party received 0.24% of the vote.^[4]

As a result, the party did not receive any seats in the State Duma. However, Bryntsalov won the Orekhovo-Zuyevo constituency and joined the "People's Deputy" parliamentary group. In 2001, the party disbanded and joined the United Russia party.
