Mar Abdisho IV Maron (Classical Syriac: ܥܒܕܝܫܘܥ ܪܒܝܥܝܐ ܡܪܘܢ‎) was the second Patriarch of the Chaldean Catholic Church, from 1555 to 1570. Abdisho, whose name is spelled in many different ways (Abdisu, Abd-Jesu, Hebed-Jesu, Abdissi, Audishu) meaning Servant of Jesus, was born in Gazarta on the River Tigris, son of Yohannan of the house of Mari. He entered in the monasteries of Saint Antony and of Mar Ahha and Yohannan, and in 1554 was consecrated metropolitan bishop of Gazarta by Shimun VIII Yohannan Sulaqa.
