Dadisho Qatraya[1] or Dadisho of Qatar (Classical Syriac: ܕܕܝܫܘܥ ܩܛܪܝܐ;[2] late 7th century) was a Nestorian monk and author of ascetic literature in Syriac.
[3] Originally from Beth Qatraye (eastern Arabia), he became attached first to the unidentified monastery of Rab-kennārē then later to those of Rabban Shabur (near Shushtar in Khuzestan) and of the Blessed Apostles.
[4] Giuseppe Simone Assemani identified him with Dadisho of Mount Izla, who lived a century earlier.
[4][12] The Arabic version of the Abba Isaiah commentary describes Dadisho as a disciple of Isaac of Nineveh.
[12] Dadisho is the earliest writer to credit an Egyptian monk, Mar Awgin (a figure he may have invented), with introducing monasticism to Mesopotamia in the 4th century.
