The Estádio das Antas (pronounced [ɨʃˈtaðju ðɐz ˈɐ̃tɐʃ]; officially Estádio do Futebol Clube do Porto [ɨʃˈtaðju ðu futɨˈβɔl ˈkluβɨ ðu ˈpoɾtu]) was the third (and longest occupied) stadium of the Portuguese football side FC Porto.

While the Poente had four, both Maratona and Arquibancada had five, and both Superiores (upper tiers) had nine, but two in Norte were reserved for away supporters.

For matches, low turnout from away fans, in contrast to that expected from Porto supporters, so the away fan sector was often reduced in size by half.

In the past there were other divisions, such as splitting the Superior stands between the original and the new terraces built after the 1986 capacity increase.

The national team first played in the stadium in 1952 and held its last game there in 2003.
