La Baronia de Rialb (Catalan pronunciation: [la βaɾoˈnia ðe riˈalp]) is a municipality in the comarca (county) of the Noguera in Catalonia, Spain. The territory is crossed by the river Rialb and the river Segre. The capital city is Gualter; before it had been La Torre de Rialb.
The municipality is formed by the union of old and tiny hamlets and parishes, which in total accounts for twenty-three Romanesque churches, which is the largest number of such churches in Catalonia.
