A mohel is a Jewish man trained in the practice of brit milah, the "covenant of male circumcision". The equivalent for a woman circumciser is mohelet.

The brit milah or bris is the ceremony of circumcision in Judaism and Samaritanism, during which the prepuce is surgically removed. According to the Book of Genesis, God commanded the biblical patriarch Abraham to be circumcised, an act to be followed by his male descendants on the eighth day of life, symbolizing the covenant between God and the Jewish people. Today, it is generally performed by a mohel on the eighth day after the infant's birth and is followed by a celebratory meal known as seudat mitzvah.
