Quarteira (pronounced [kwɐɾˈtɐjɾɐ], locally [kwɐɾˈteɾɐ]) is a Portuguese civil parish, in the municipality (concelho) of Loulé in the Algarve.

[3] The settlement of the region dates back to, at least, the Roman occupation of the Iberian Peninsula (at one time confused with the village of Carteia).

[4] For several centuries, Quarteira was a modest fishing village, situated on the edge of a 3 kilometres (1.9 mi) beach, encircled by pines.

From the Atlantic coast, the frontier with its neighbours extends northwest along the Ribeira de Algibre, before following the M526 municipal roadway to the Estrada Nacional EN125 in Maritenda.

From here, the border travels southeast along the EN125 until just after the N396 motorway, where it then divides along a ravine southwest towards the Atlantic Ocean, alongside the Royal Golf Course.
