Fourth federal electoral district of Hidalgo

The fourth federal electoral district of Hidalgo (Distrito electoral federal 04 de Hidalgo) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of the seven currently operational districts in the state of Hidalgo.
