Taüll (Catalan pronunciation: [təˈuʎ]) is a town in the province of Lleida, in Catalonia, Spain.

According to Catalan linguist Joan Coromines, the name Taüll comes from the Ibero-Basque roots (a) ta-uri > (a) ta-uli: "the village of the (mountain's) door".

Further juridic conflicts made both counties join again and until the early 12th century the region didn't have any sort of stability.

The lords of Erill had the villages of Taüll and Boí under their jurisdiction, whose amassed wealth allowed all the rustic churches in the valley to be renewed, building the churches of Sant Climent, Sant Martí (destroyed by an avalanche in the 1970s) and Santa Maria, featuring a richly decorated Romanesque architecture with outstanding liturgical furniture.

Taüll's economy is based on summer and winter tourism, aside from its aforementioned Romanesque heritage, the town also has a variety of hotels, restaurants and guided hikes.
