Ignatius bar Wahib^{[nb 1]} (Syriac: ܒܪ ܘܗܝܒ, Arabic: ابن ُوهيب)^[1] was the Syriac Orthodox Patriarch of Mardin from 1293 until his death in 1333.

Joseph Badr al-Din Zakhi bar Wahib was born at Korinsha in the Tur Abdin in the 13th century, and was the son of Abraham.^[4] He was raised at Mardin,^[5] and became a monk at the nearby monastery of Saint Ananias.^[4] Patriarch Philoxenus I Nemrud consecrated bar Wahib as archbishop of Mardin in 1287, upon which he assumed the name Ignatius.^[6]

He was elected as the patriarch of Mardin at a synod at the monastery of Saint Ananias at the beginning of January 1293, and was consecrated by Ignatius, archbishop of Qartmin.^[7] In 1303 or 1304, he convened a synod at the monastery of Saint Ananias, in which he issued ten canons, and was attended by five bishops.^[8][9] He was credited with performing three miracles at Mardin that were reportedly recognised by both Christians and Muslims.^[10] Bar Wahib served as patriarch of Mardin until his death in 1333.^[4] As patriarch, Bar Wahib ordained twenty bishops.^[4]

Bar Wahib wrote two books on Syriac and Arabic phonetics, and a liturgy in 1304.^[11] As well as this, he wrote a treatise on the definition of prayers and rituals.^[11]
