The Azores are officially the Autonomous Region of the Azores (Região Autónoma dos Açores), is one of the two autonomous regions of Portugal (along with Madeira). It is an archipelago composed of nine volcanic islands in the Macaronesia region of the North Atlantic Ocean, about 1,400 km (870 mi) west of Lisbon, about 1,500 km (930 mi) northwest of Morocco, and about 1,930 km (1,200 mi) southeast of Newfoundland, Canada.

There are nine major Azorean islands and an islet cluster, in three main groups. These are Flores and Corvo, to the west; Graciosa, Terceira, São Jorge, Pico, and Faial in the centre; and São Miguel, Santa Maria, and the Formigas islets to the east. They extend for more than 600 km (370 mi) and lie in a northwest–southeast direction. All of the islands have volcanic origins, although some, such as Santa Maria, have had no recorded activity in the time since the islands were settled several centuries ago. Mount Pico, on the island of Pico, is the highest point in Portugal, at 2,351 m (7,713 ft). If measured from their base at the bottom of the ocean to their peaks, the Azores are among the tallest mountains on the planet.
