Roseann "Rosie" O'Donnell (born March 21, 1962) is an American stand-up comedian, actress, singer, author and media personality. She has also been a magazine editor and continues to be a celebrity blogger, LGBT rights activist, television producer and collaborative partner in the LGBT family vacation company R Family Vacations.

Raised Roman Catholic, O'Donnell lost her mother to cancer as a pre-teen and has consistently stressed values of protecting children and supporting families throughout her career. O'Donnell started her comedy career while still a teenager and her big break was on the talent show Star Search when she was twenty years old. A TV sitcom and a series of movies introduced her to a larger national audience and in 1996 she started hosting The Rosie O'Donnell Show which won multiple Emmy awards.

During her years on The Rosie O'Donnell Show she wrote her first book, a memoir called Find Me and developed a reputation for being "the queen of nice" as well as a reputation for charitable philanthropy. She used the book's $3 million advance to establish her own For All Kids foundation and promoted numerous other charity schemes and projects encouraging other celebrities on her show to also take part. O'Donnell came out stating "I'm a dyke!" two months before finishing her talk show run, saying that her primary reason was to bring attention to gay adoption issues. O'Donnell is a foster—and adoptive—mother. She has since continued to support many LGBT causes and issues.
