Gerard Anthony "Tony" Bill (born August 23, 1940) is an American actor, producer, and director. He produced the 1973 movie The Sting, for which he shared the Academy Award for Best Picture with Michael Phillips and Julia Phillips.

He majored in English and art at the University of Notre Dame in South Bend, Indiana, from which he graduated in 1962. Bill began his career as an actor in the 60s, first appearing on screen as Frank Sinatra's ingenuous younger brother in Come Blow Your Horn (1963). Bill specialized in likeable but none-too-bright juveniles and young leads. His acting credits include None But the Brave (1965), You're A Big Boy Now (1966), Never a Dull Moment (1968), Ice Station Zebra (1968), Shampoo (1975), The Little Dragons (1980), Pee-wee's Big Adventure (1985), and Less Than Zero (1987).
