This article lists political parties in Mexico.

Mexico has a multi-party system, which means that there are more than two dominant political parties. Nationally, there are three large political parties that dominate: the PRI, the PAN, and the PRD. Other smaller political parties survive in isolation or by forming local coalitions with any of the big three.

The parties

Following the 6 July 2003 midterm election, Mexico has six nationally recognized political parties. National recognition is given to those parties that secure representation in Congress (effectively, a share of the popular vote greater than 2%).

Under Mexican law, parties are listed in the order in which they were first registered, thus:

• PAN: the National Action Party (Partido Acción Nacional) – the right-wing party of incumbent President Vicente Fox. This party believes in political professionalism and free enterprise. Among its members are an (indeterminate) number of Roman Catholic radicals who believe the party should impose Catholic morality as law.
• PRI: the Institutional Revolutionary Party (Partido Revolucionario Institucional) – in power, under different names, at the local, state, and national levels for most of the 20th century. For the current legislative period (2003–2006), still the largest party in both chambers of Congress.
• PRD: the Party of the Democratic Revolution (Partido de la Revolución Democrática) – Born as a Democratic Front in the 1988 elections. Its candidate then, Cuauhtémoc Cárdenas, lost the 1988 presidential election under dubious circumstances, and thus the party consolidated itself. It is currently in power in the Federal District under Andrés Manuel López Obrador, and in several other states.
• PT: the Labour Party (Partido del Trabajo)
• PVEM: the Green Ecological Party of Mexico (Partido Verde Ecologista de México)
• Convergencia: Convergence

In terms of their congressional representation and share of the national vote, the first three can be considered major parties. The other three are, in comparison, minor.
