Workers Party of Jamaica

The Workers Party of Jamaica (WPJ) was a Marxist-Leninist political party in Jamaica. WPJ was founded on 17 December 1978 by Trevor Munroe, along with Elean Thomas and others. Trevor Munroe, a Rhodes scholar from Oxford University, served as its general secretary. The forerunner of WPJ was the Workers Liberation League.

WPJ was a "critical ally" of the People's National Party (PNP) of Michael Manley. The 1980 elections resulted in a victory of the rightist Jamaica Labour Party. Manley's association with the communist WPJ may have contributed to his defeat.

The WPJ youth organization, Young Communist League of WPJ, was a member of the World Federation of Democratic Youth.

By 1992, the WPJ was defunct.
