Urgellet (Catalan pronunciation: [urʒəˈʎɛt], locally: [uɾdʒeˈʎet]) is a historical territory and a natural region of Catalonia. It is located in the Pyrenees exactly in the actual administrative comarca of Alt Urgell, that last includes Baridà, Urgellet and the banks of Oliana, Peramola and Bassella.
The territory of Urgellet is almost Alt Urgell, except the Eastern (Baridà) and the southern sector. The Strait of Mollet represents the natural boundary between Urgellet and Baridà.
The history of Urgellet is highly related to Sedes Urgelli (La Seu d'Urgell or city of Urgell), the Bishop of Urgell and the County of Urgell. In the latter case, the territory Urgellet was leading the county, with capital in la Seu d'Urgell, and extended southwards up to the comarques of Urgell and Pla d'Urgell, among others. For this reason some towns and two comarques in Lleida contain the name of Urgell that has its origin in the city of Urgell and Urgellet region.
The name Urgell, as linguist Joan Coromines think, has a pre-Roman origin. The author interprets the meaning is related to the presence of water, which is plausible if this is the origin of the name specifically Pyrenean.
