Mallorca or Majorca, is the largest island of the Balearic Islands, which are part of Spain, and the seventh largest island in the Mediterranean Sea.

The capital of the island, Palma, is also the capital of the autonomous community of the Balearic Islands. The Balearic Islands have been an autonomous region of Spain since 1983.[4] There are two small islands off the coast of Mallorca: Cabrera (southeast of Palma) and Dragonera (west of Palma). The anthem of Mallorca is "La Balanguera".

Like the other Balearic Islands of Menorca, Ibiza, and Formentera, the island is a highly popular holiday destination, particularly for tourists from the Netherlands, Germany, and the United Kingdom. The international airport, Palma de Mallorca Airport, is one of the busiest in Spain; it was used by 28 million passengers in 2017, with use increasing every year between 2012 and 2017.

Mallorca and the other Balearic Islands are geologically an extension of the fold mountains of the Betic Cordillera of Andalusia. They consist primarily of sediments deposited in the Tethys Sea during the Mesozoic era. These marine deposits have given rise to calcareous rocks which are often fossiliferous. The folding of the Betic Cordillera and Mallorcan ranges resulted from subduction of the African plate beneath the Eurasian plate with eventual collision.
Tectonic movements led to different elevation and lowering zones in the late Tertiary period, which is why the connection to the mainland has been severed at the current sea level.

The limestones, which predominate throughout Mallorca, are readily water-soluble, and have given rise to extensive areas of karst. In addition to limestone, dolomitic rocks are mainly present in the mountainous regions of Mallorca; the Serra de Tramuntana and the Serres de Llevant. The Serres de Llevant also contain marl, the more rapid erosion of which has resulted in the lower elevations of the island's southeastern mountains. Marl is limestone with a high proportion of clay minerals. The eroded material was washed into the sea or deposited in the interior of the island of the Pla de Mallorca, bright marls in the north-east of the island and ferrous clays in the middle of Mallorca, which gives the soil its characteristic reddish colour.
