The Workers' Socialist Party (Spanish: Partido Socialista de los Trabajadores, PST) was a socialist political party in Mexico. The PST was founded in 1975 by Rafael Aguilar Talamantes, Graco Ramírez and Juan Ignacio del Valle, though the party did not obtain its official registration until 1979. The party nominated Cándido Díaz Cerecedo in the 1982 presidential election.

The PST won 10 plurinominal seats in the Chamber of Deputies in their first elections in 1979. Three years later, they gained one seat. Finally, the PST gained one additional seat in the 1985 midterm elections.

However, the PST became a satellite party of the ruling Institutional Revolutionary Party (PRI). The PST was renamed the Party of the Cardenist Front of National Reconstruction in 1987.
