Bill Hayes (born June 5, 1925) is an American actor, best known for his role as Doug Williams on Days of Our Lives.
Hayes originally played the role from 1970 to 1984. He returned in 1986 and 1987, as well as 1993 and 1996. Most recently, he has been on the show since 1999, only to have his character killed off in the spring of 2004. In an elaborate plot hatched by writer James E. Reilly, he turned up alive on a tropical island and went home to his wife.
He has been married to fellow Days of Our Lives co-star Susan Seaforth since 1974. His character's partnership with Seaforth's character, Julie, is widely believed to be the first supercoupling on the American daytime serials.
