Castres (Occitan: Castras) is a commune in the region of Midi-Pyrénées, in southwestern France. It is the sous-prefecture (capital) of the arrondissement of the same name in the Tarn department.

It is also the capital of 3 cantons: Castres-1, Castres-2 and Castres-3.

Castres is (after Toulouse, Tarbes and Albi) the fourth largest industrial centre of the mainly rural Midi-Pyrénées région and the largest in that part of Languedoc between Toulouse and Montpellier.


The name of the town comes from Latin castrum, and means "fortified place".

Castres grew up round the Benedictine abbey of Saint Benoît. Castres became an important stop on the international pilgrimage routes to Santiago de Compostela in Spain because its abbey-church, built in the 9th century, was keeping the relics of Saint Vincent, the renowned martyr of Spain. It was a place of some importance as early as the 12th century, and ranked as the second town of the Albigeois behind Albi.


Castres is in southern France, in the southwestern part of the Tarn department, to the north of the Montagne Noire, a mountain range in central southern France. Castres is crossed from north to south by the Agout river, a tributary of the Tarn.

The commune has an area of 98.17 km2 (37.90 sq mi) and its average altitude is 259 m (850 ft); at the city hall, the altitude is 173 m (568 ft)..
