Alexander I was pope from about 106 to 115. He has been identified, without any foundation, with Alexander, a martyr of the Via Nomentana, whose day is the 3rd of May. St. Irenaeus of Lyons, writing in the second century, reckons him as the fifth pope in succession from the Apostles, though he says nothing of his martyrdom.
