Ignatius V Moussa Qattan, (or Cattan, Kattan, Quattan, 1756–1833) was patriarch of the Melkite Greek Catholic Church from 1816 until 1833.
He was the nephew of Soleiman Qattan, who ran the printing press of the monastery of Saint John at Choueir after the death of Abdallah Zakher.
His being diocesan priest allowed him to be outsider in the conflict about the two monastic orders that marked the history of the 18th century Melkite Catholic Church.
His conciliative and gently nature, and later his blindness and paralysis, led him to be a weak Patriarch, subject to bad advisers.
The violent persecutions halved the Catholic Melkite population of Aleppo and Damascus in about ten years.
