The Baldwin brothers, Alec (born 1958), Daniel (1960), William (1963) and Stephen (1966) are four American brothers who have all become actors.

Born in Massapequa, New York, the Baldwin brothers are the children of Alexander and Carol Baldwin. The brothers have two sisters, Jane and Elizabeth.

For some unknown reason South Park creators Trey Parker and Matt Stone have a vendetta against the Baldwin brothers. In South Park and Team America: World Police the Baldwins are portrayed as ignorant actors who deserve to be hated.

Actor Adam Baldwin is not related to the Baldwin brothers .
