Joseph Breen (born July 5, 1958) is an American soap opera actor. He was born in Katonah, New York.

He played contract parts on both Guiding Light and Loving before being offered his most front-burner role to date: that of Lisa’s long-lost son, Scott Eldridge, on As the World Turns. He started on As the World Turns in 1991, while he was still making appearances as another character on Loving.

In 1993, the sponsor of the show, Procter & Gamble, was very unhappy when word leaked to the tabloids (most notably the National Enquirer) that Breen had AIDS. He was forced to tell his castmates that the rumors were true. The setside rumors were that P&G wanted Breen to voluntarily leave the show, and when he wouldn’t, he was forced to tape many scenes in which he was scantily clad. Reportedly, taping the scenes made him uncomfortable as both his muscle and body fat had already begun the process of atrophy, and it was at this time that he left.

In 1995, Breen was interviewed in a television miniseries titled The Celluloid Closet , which described the portrayals of homosexuals in film and television.

While he is still living, he has chosen to keep a lower profile as of late.
