Dorotheus of Gaza (d. 565), was a Christian monk and abbot recognized as a saint in Catholic and Orthodox churches.

He was born in Antioch, Syria around 506. Later he would go to Gaza where he joined a monastery where he was discipled by the elders Barsanuphius and John. At the monastery he was appointed to be the guest-master and then later the head of the infirmary where he ministered to the sick. Around 540 he founded his own monastery close by. There as the abbot he wrote a number of discourses to help the monks under his authority. These included topics such as "the fear of God", "humility", and "not judging your neighbor." A large number of these discourses have survived and have been translated into a number of languages from the original Greek.
