The Lavedan (French pronunciation: [lavdɑ̃]; in Gascon eth/lo Lavedan, /et/lu laβedã/), or occasionally vallées des Gaves, denotes a mountainous natural region of France, located at the heart of the Pyrénées, and forms a group of valleys upstream of Lourdes.

The Lavedan is historically part of the Gascony province and of the county of Bigorre. Today, it is situated in the Hautes-Pyrénées department in the Occitanie region.

Etymology

The name "Lavedan" is documented under ancient forms:^[2] in pago Lavetanense (v. 860),^[3] Levitanensis vicecomes (v. 980),^[3] vicecomites Levitanicæ vallis (v. 1060),^[4] Ramundus de Levitania (1095),^[5] homines Baredgie et Levitani (v. 1110),^[6] A. de Laueda (1114),^[7] Aramon Garsie de Lavedan (1283),^[8] terram de Lavedaa (1285).^[9]

Il is made up of the Latin -etan, -itan suffix, typically present in names of iberian peoples. Le radical est Lau- / Leu-.

Hydrography

Delimitation

It is separated from Aragon by the France–Spain border, traversable by numerous mountain passes.
