The complete list of Presidents of the Portuguese Republic consists of the 20 heads of state in the history of Portugal since the October 5, 1910 revolution that installed a republican regime. This list includes not only those persons who were sworn into office as President of Portugal but also those who de facto served as head of state since 1910. This is the case of Teófilo Braga who served as President of the Provisional Government after the republican coup d'état. Also Sidónio Pais, Mendes Cabeçadas, Gomes da Costa, as well as Canto e Castro and Óscar Carmona in their early months, weren't sworn into office as President of the Republic, usually being the President of the Ministry (Prime Minister), but de facto accumulation this functions with that of the Head of State. See the notes for more information.

The numbering reflects the uninterrupted time in office served by a single person. For example, Jorge Sampaio served two consecutive terms and is counted as the 19th president (not the 19th and 20th). Teófilo Braga served as the first and sole president of the Provisional Government, and therefore is not considered the first President, although he would serve again as head of state and be the 2nd president after Manuel de Arriaga's resignation. Bernardino Machado served two non-consecutive terms and is counted as both the 3rd and the 8th president. Because of this, the list below contains 20 presidencies, but only 19 presidents.

The current President of Portugal is Aníbal Cavaco Silva, winner of the 2006 presidential election.
