Celidonius is the traditional name ascribed to the "man born blind" whom Jesus healed in the Gospel of John 9:1-38. This tradition is attested in both Eastern and Western Christianity.
One tradition ascribes to St. Celidonius the founding of the Christian church at Nîmes in Gaul (present-day France).
Saint Demetrius of Rostov, in his Great Synaxarion, also mentions that the blind man's name was Celidonius.
In the Eastern Orthodox Church, the account of the healing of Celidonius is recounted on the Sunday of the Blind Man, the Sixth Sunday of Pascha (Easter). Many hymns concerning the healing and its significance are found in the Pentecostarion, a liturgical book used during the Paschal season.
