Democratic Action (Spanish: Acción Democrática, AD) is a Venezuelan social democratic and center-left political party established in 1941. The party played an important role in the early years of Venezuelan democracy, leading the government during Venezuela's first democratic period (1945–1948). A decade of dictatorship under Marcos Pérez Jiménez followed, which saw AD excluded from power. With the advent of democracy in 1958, four Presidents of Venezuela came from Acción Democrática from the 1950s to the 1990s during the two-party period with COPEI.
