Pere d'Urtx (Catalan pronunciation: [ˈuɾtʃ] OORTCH) was Bishop of Urgell from 1269 to 1293. He became the first Episcopal Co-Prince of Andorra when he signed the paréage establishing joint-sovereignty over the territory with Roger-Bernard III, Count of Foix in 1278.
The paréage ended almost a century of conflict over the territory between successive Bishops of Urgell, on the one hand, and Viscounts of Castellbò and Counts of Foix, on the other, and effectively established the modern state of Andorra.
