The Baldwin brothers are a group of four American brothers who are professional actors: Alec Baldwin, Daniel Baldwin, William Baldwin, and Stephen Baldwin. They come from a family of performers and have had notable careers in film and television. Alec Baldwin is the oldest and most well-known of the brothers, with several Emmy and Golden Globe awards. The brothers are descendants of early American settlers, including passengers of the Mayflower. They also have sisters and extended family members involved in the entertainment industry.

In addition, there is a musical duo called The Baldwin Brothers based in Chicago, but they are unrelated to the Baldwin acting family. This duo, consisting of Jason Hinkle and TJ Widner, performs electronica and lounge music.
