Desan (died 355AD) was a bishop of the Christian Church.
He was a resident of Bizabda in Mesopotamia during the reign of Shapur II.[1] He refused to turn away from the Christian faith and was on that basis transported to Persia where he was killed in 355. He was accompanied in martyrdom by a number of others, including: Heliodorus, another Christian bishop; Marjab, a Christian priest; Abdjesus, and 270 others.
They are all collectively commemorated with a feast day on April 9.
