Anthony Criss aka Treach, is an American rapper and actor. He is perhaps best known as the lead rapper of the hip hop group Naughty by Nature.

With Naughty by Nature, Treach worked with fellow group members Vin Rock and DJ Kay Gee. Sometimes he shared verses on songs with Vin Rock, but often, especially on the group's earlier albums, Treach was the sole performer on the song. Examples of this are some of the group's most well-known singles from their self-titled second album, such as "O.P.P.," and "Ghetto Bastard".

Treach's physique has helped him land roles in crime films, television crime dramas and as a leading man in romance films, including a full frontal in the 2001 crime comedy Love and a Bullet.
