'Umar ibn Ibrahim ibn Waqid al-'Umari (Arabic: عمر بن إبراهيم بن واقد العمري) was a ninth century governor of the Yemen for the Abbasid Caliphate.
A descendant of the second Rashidun caliph 'Umar ibn al-Khattab, 'Umar was appointed as governor shortly after the death of the caliph al-Amin in 813. He remained in office for less than a year, during which time he carried out instructions to arrest his predecessor Yazid ibn Jarir al-Qasri, and was dismissed in mid-814.
