The third federal electoral district of Nayarit (Distrito electoral federal 03 de Nayarit) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of three such districts in the state of Nayarit.
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 third district was created as part of the 1977 political reforms and was first contended at the 1979 election; prior to that, Nayarit comprised only two federal electoral districts.[1]
