The National Democratic Front (Spanish: Frente Democrático Nacional) was a coalition of left-wing Mexican political parties created to compete in the 1988 presidential elections, being the immediate predecessor of the Party of the Democratic Revolution (PRD). It was result of an agglutination of small political left and center-left forces with dissident members from the Institutional Revolutionary Party (PRI). Their candidate for the presidential election was Cuauhtémoc Cárdenas.
