Pope Kedron of Alexandria, or Cerdo, served as Patriarch of Alexandria during the reign of the emperor Trajan. According to the Church historian Eusebius, he was the third bishop to occupy the see. However, if Saint Mark is considered to be the first, then Kedron would in fact be the fourth. He presided between 96 and 106.
He was one of the people baptised by Saint Mark in Alexandria and was marytered on 21 Paoni, 15 June 106 AD. He is commemorated in the Coptic Synaxarion on the 21st day of Ba'unah.
