Mattathias ben Theophilus (c. 60 CE) was the Jewish High Priest (Kohen Gadol) at the start of the Jewish Revolution, and was overthrown by Revolutionary forces.
A minority of scholars believe him to be the same as the Theophilus mentioned in the New Testament books of Luke 1:3 and Acts 1:1. One author argues that Mattathias ben Theophilus was the father of Josephus.
