Sexenio is the popular term for the term of office on the President of Mexico. Under Article 83 of the Mexican Constitution, the president is limited to a single six-year term, and no one who holds the office even on a caretaker basis is permitted to run for or hold the office again. It is one of the country's most important political institutions, because it is one of the few significant limitations on executive power in Mexico, which is strong at local, state, and national levels. The sexenio is a reaction to the failed experiment of re-election in Mexico during part of the Porfiriato era (1876–1911).

In addition to restricting the presidency, state governors also face this restriction; no one elected as a governor may ever hold the post again, even on an interim basis.
