Ovinius Gallicanus (floruit 293 – 317) was a senator of the Roman Empire, probably the first Christian Roman consul.

In 293 or 300 he was the curator of Teanum Sidicinum. On 4 August 316 he is attested as praefectus urbi of Rome, as successor to Gaius Vettius Cossinius Rufinus, and kept the office at least until 15 May 317, the year he was also consul, to be succeeded by Septimius Bassus.

He might be identified with the Gallicanus who gave some lands to the church of Saints Peter, Paul, and John the Baptist in Ostia.
