John William Albaugh Sr. (September 30, 1837 – February 11, 1909), was an American actor and manager.

Born in Baltimore, Maryland, it was there that Albaugh made his first real appearance on the stage as the title character in a play called Brutus, or the Fall of Tarquin (1855), on a stage managed by Joseph Jefferson.

Of his many subsequent impersonations, perhaps the best-known is that of Louis XI, at what later became Daly's Theatre in New York.

He owned the new Lyceum Theatre in Baltimore,[1] where he made his last appearance in 1899 before retiring from the stage.

Albaugh died at the home of his daughter in Jersey City from heart disease.
