The Democratic Party of Mendoza (Spanish: Partido Demócrata Mendoza) is a provincial conservative party in Mendoza Province, Argentina. It was founded around 1930.
Since the return of the democracy in 1983, the party has been the third political force in Mendoza, except in 1999 when it won the second position in the elections.
It is a member of the national Recrear electoral alliance led by Ricardo López Murphy although in 2007 it supported the presidential bid of Roberto Lavagna rather than López Murphy.
