Pallars Sobirà (Catalan pronunciation: [pəˈʎaz suβiˈɾa], locally: [paˈʎaz soβiˈɾa]) is a comarca (comparable to a county or shire in much of the English-speaking world) in the mountainous northwest of Catalonia, Spain. The name means "Upper Pallars", distinguishing it from the more populous (and less mountainous) Pallars Jussà to its southwest. Its capital and largest municipality is Sort. Pallars Sobirà contains the largest lake in the Pyrenees, the lake of Certascan, and the highest peak in Catalonia, the Pica d'Estats (3,143 m).
