The Lagar of Diogo Fernandes Faleiro (Portuguese: Lagar de Diogo Fernandes Faleiro) is an ancient winepress, hewn from riverbank rocks, situated in the civil parish of Santo Espírito in the municipality of Vila do Porto, in the Portuguese archipelago of the Azores.

Constructed after 1579 by Diogo Fernandes Faleiro, the press was known for producing 11,000 litres (2,900 US gal) of wine annually.

Frutuoso also expanded its owner, stating his philanthropic works associated with early migration: The lagar is located at the mouth of the Ribeira de Aveiro, in the village of Maia, on the southwestern coast of the island.

The wine-press is an archaic form hewn from a large boulder and rocks along the ravine's left bank.

It is identifiable for the roughly square basin that was used to collect and press grapes, with an opening from where the juice was extracted.
