The prime minister of the Portuguese Republic (Portuguese: primeiro-ministro da República Portuguesa) is the head of the Government of Portugal. The officeholder coordinates the actions of all ministers, represents the Government as a whole, reports their actions and is accountable to the Assembly of the Republic, in addition to keeping the president of the Republic informed.

There is no limit to the number of mandates as prime minister. They are appointed by the president of the Republic, after the legislative elections and after an audience with every leader of a party represented at the Assembly. It is usual for the leader of the party which receives a plurality of votes in the elections to be named prime minister.

The official residence of the prime minister is a mansion next to São Bento Palace, which, in confusion, is also often called "São Bento Palace", although many prime ministers did not live in the palace during their full mandate.
