Bernie Leadon (born July 19, 1947 in Minneapolis, Minnesota) is an American musician, best known as a founding member of the country rock band the Eagles.

Leadon cut his teeth with various Southern California bluegrass and country rock groups in the 1960s, such as The Scottsville Squirrel Barkers (with future Byrd Chris Hillman), Hearts & Flowers, Dillard & Clark, and The Flying Burrito Brothers in the 1960s, featuring his work on dobro, banjo and mandolin, as well as guitar.

Introduced, and attracted, to the songwriting, singing and instrumental skills of Glenn Frey, Don Henley and Randy Meisner while all were members of a backing band in the employ of Linda Ronstadt, the quartet tendered their resignation en masse and formed their own group, dubbing themselves "the Eagles" as a nod to seminal folk rockers the Byrds in 1971. Leadon used his boyhood choir training to arrange intricate harmony vocals on the Eagles' first few albums, and displayed his considerable multi-instrumental skills to great effect. He also wrote or co-wrote several songs, including the band's second hit, "Witchy Woman."
