The patron saint of Ittiri is Saint Peter in Chains, celebrated on 29 June in the Church of San Pietro in Vincoli.
Since 1985, generally in the third week of July, the Ittiri Folk Festa is held, an international festival of folk songs, music and dance with a parade through the town's streets and a craft exhibition. The town also holds the Nuraghe Abbarghente and the Nuraghe Chentu Cheddas.
