The Suessetani were a pre-Roman people of the Iberian Peninsula that dwelt mainly in the plains area of the Alba (Arba) river basin (a northern tributary of the Ebro river), in today’s Cinco Villas, Aragon, Zaragoza Province (westernmost Aragon region) and Bardenas Reales area (southernmost Navarra region), west of the Gallicus river (today's Gállego river), east of the low course of the Aragon river and north of the Iberus ( Ebro) river, in the valley plains of this same river. Their location, in relation to other tribes, was south of the Iacetani ( Aquitanian tribe), west of the Vescetani or Oscenses ( Iberian tribe) north of the Lusones and Pellendones ( Celtiberian tribes), also north of the Sedetani ( Iberian tribe), and southeast of the Vascones ( Aquitanian tribe or people).
Corbio was the capital of the Suessetani and an important fortified city, yet unlocated (maybe between Sangüesa and Sos del Rey Católico).
