The Baetic System or Betic System () is one of the main systems of in Spain. Located in the southern and eastern Iberian Peninsula, it is also known as the Cordilleras Béticas (Baetic Mountain Ranges) or Baetic Mountains. The name of the mountain system derives from the ancient Roman region of Baetica, one of the Imperial Roman provinces of ancient Hispania.
Geography
The Baetic System is made up of multiple mountain ranges that reach from western
Andalusia to the Region of Murcia, southern Castile-La Mancha and southern Land of Valencia. To the north, the Baetic Ranges are separated from the
Meseta Central and the
Sierra Morena by the basin of the
Guadalquivir. The Iberian System rises north of the eastern part of the
Prebaetic System, the northernmost part of the Baetic System. The mountain ranges that are part of this system are generally aligned \along a southwest-northeast direction.
[ Granada Natural - Las Zonas Externas]
The best-known range of the Baetic System is the Sierra Nevada, which contains the Mulhacén, the highest mountain in continental Spain and in the Iberian Peninsula.
The Rock of Gibraltar is also considered part of the Baetic System,[ A Guide to the Upper Rock Nature Reserve ] but not the Cabo de Gata area further east which includes rocks of volcanic origin.[ European geoparks website ]
Geology
The Baetic System as a geological feature belongs to a larger
orogeny usually called the
Gibraltar Arc, which represents the westernmost edge of the
Alpine Orogeny. The
geodynamic mechanisms responsible for its formation are so far relatively unknown.
[Wes Gibbons & Teresa Moreno, The geology of Spain. Geological Society of London, 2003, ]
Geologically the Rif mountains in Morocco and the Serra de Tramuntana in the island of Majorca are, respectively, Southwestern and Northeastern extensions of the Baetic System.[ Dan Davis, Commercial Navigation in the Greek and Roman World]
The Gibraltar Arc geological region follows the Moroccan coast from Oujda in the east to Tangier in the west, then crosses the Strait of Gibraltar and goes east again from Cádiz to Valencia and the Balearic Islands.
Ecology
The Baetic System is home to a number of Mediterranean forests, woodlands, and scrub plant communities, including shrublands,
oak woodlands,
, and
forests, which vary with elevation, soils, and topography.
The Baetic System, together with the Rif Mountains of Morocco, which face the Baetic Ranges across the Alboran Sea, is one of the Mediterranean basin's ten biodiversity hotspots, known to ecologists as the Baetic-Rifan complex. The Baetic mountains are home to a rich assemblage of Mediterranean plants, including a number of relict species from the ancient , which covered much of the Mediterranean basin millions of years ago when it was more humid.

The Baetic System is divided into the following sub-chains (from south to north):
