The Banu Ghaniya, distant relatives of the Almoravids, are a Sanhaja Berber dynasty.

They are appointed as governors of the Balearic Islands in 1126.

Following the collapse of the Almoravid power at the hand of the Almohads in the 1140s, the Banu Ghaniya continue to govern the Balearic Islands as independent emirs until about 1203, with a brief interruption in the 1180s.

The Banu Ghaniya consider themselves as heirs of the Almoravids, and make a determined attempt to reconquer the Maghreb (and in particular Ifriqiya) from about 1180 onwards.
