Umar ibn Hafs ibn Shuayb ibn Isa al-Balluti (died 855), surnamed al-Ghaliz ("the Fat") and later al-Iqritishi ("the Cretan"), and usually known as Abu Hafs (أبو حفص, in Greek sources Ἀπόχαψ[ις], Apochaps[is]), was the leader of a group of Andalusian refugees who seized control of Alexandria and, after being expelled from the city by the Abbasids, conquered the Byzantine island of Crete, becoming the first Emir of Crete.
