Abu Hafs Umar al-Murtada (Arabic: أبو حفص المرتضى عمر بن أبي إبراهيم اسحاق بن يوسف بن عبد المؤمن‎; died 1266) was an Almohad caliph who reigned over part of Morocco from 1248 until his death.

During his time as caliph, the area of Morocco under Almohad control was reduced to the region around and including Marrakech. He was forced to pay tribute to the Marinids. He was ousted by his cousin Abu al-Ula al-Wathiq Idris with the help of Marinid ruler Abu Yusuf Yaqub ibn Abd Al-Haqq, with Idriss II then proclaiming himself as caliph.
