Theudas (; Greek: Θευδᾶς; died c. 46 CE) was a Jewish rebel of the 1st century AD. Scholars attribute to his name a Greek etymology and according to Thayer, is a contraction of Theodore, and Hitchcock, for his part, says it means "flowing with water" , although with a Hellenist-styled ending. At some point between 44 and 46 CE, Theudas led his followers in a short-lived revolt.
