Colima's two federal electoral districts since 2022District Col-I shaded blue (2005)
The first federal electoral district of Colima(Distrito electoral federal 01 de Colima) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of two such districts in the state of Colima.
It elects one deputy to the lower house of Congress for each three-year legislative period, by means of the first-past-the-post system.
The district's head town (cabecera distrital), where results from individual polling stations are gathered together and collated, is the state capital, the city of Colima.[2]
