William Mills "Bill" Irwin (born April 11, 1950) is an American actor, clown, and comedian. He is best known for his vaudeville-style stage performances and has been noted for his contribution to the renaissance of American circus during the 1970s.

He is also known as Mr. Noodle on Sesame Street 's "Elmo's World". Irwin was born in Santa Monica, California, the son of Elizabeth (née Mills), a teacher, and Horace G. Irwin, an aerospace engineer.

Irwin has created several highly regarded stage shows that incorporate elements of clowning, often in collaboration with composer Doug Skinner. These works included The Regard of Flight (1982), which ran on Broadway at the Vivian Beaumont Theatre in April 1987 for 17 performances.Largely New York (1989), Fool Moon (1993),The Harlequin Studies (2003), and Mr. Fox: A Rumination (2004).Mr. Fox is a production that Irwin has worked on for years, a biography of 19th century clown George Washington Lafayette Fox that also has autobiographical elements.
