The Democratic Unification Party (; PUD) was a centre-left political party in Honduras. PUD was founded on 29 September 1992 by the merger of four leftist clandestine or semiclandestine political parties, in the context of the changed political situation in Central America at that period, following the end of the Cold War. The PUD was legally recognised in 1993/4 and has contested various elections since 1997, gaining around 1-3% of the vote.
History
PUD was founded on 29 September 1992, by the merger of four leftist clandestine or semiclandestine political parties, namely Partido para la transformación de Honduras (PTH), Partido Revolucionario Hondureño (PRH), Partido Morazanísta de Liberación Nacional (PMLN) and Partido Renovación Patriótica (PRP). The background of the formation of PUD was the changed political situation in Central America at that period, following the end of the Cold War. Matías Funes was one of the founders of the party.
In Decree No. 189-93 of the National Congress (the Honduran parliament) of 1 October 1993, the state of Honduras legally recognised the PUD. That act was a follow-up of the Esquipulas Accords, by which the Central American governments agreed to give the revolutionary groups in the region possibilities to organize legally and participate in the political process.
Decree No. 92-94 of the National Election Tribunal of 28 January 1994, gave the PUD recognition as the fifth legally recognized political party in Honduras.
The PUD was supportive of President Manuel Zelaya in the 2009 Honduran constitutional crisis and the People's Weekly World reported that he was likely to back the PUD's presidential candidate, César Ham, in the November 2009 election. There were speculations about an alliance with the newly formed Broad Front and Zelaya's Liberty and Refoundation (Libre). In the end, the party formed an alliance with the former and nominated Andrés Pavón as their presidential candidate.
Since the rise of Libre, the party was in decline. Since 2014, the party was accused of being a "hinge party" (forming alliances with parties which have opposing views) and as "always being an ally of the National Party". In 2025, the party lost its registration since they lost all of their seats in parliament and mayors by that point.
