Bridget Moynahan Bio
Kathryn Bridget Moynahan (born April 28, 1971) is an American actress and former model whose career has spanned magazine covers, blockbuster films, and one of television’s longest-running police dramas. After beginning as a print and catalog model in New York City, she transitioned to acting in the late 1990s and built a steady career with roles in major studio features. She is best known for portraying Assistant District Attorney Erin Reagan on the CBS series Blue Bloods, a part she held from 2010 to 2024.
Over more than two decades, Moynahan has appeared in a wide range of films, from romantic comedies to action thrillers, often in supporting roles opposite leading Hollywood stars. Her work in I, Robot, The Sum of All Fears, and the John Wick franchise introduced her to wide global audiences, while her television work helped establish her as a familiar presence in American primetime drama.
Early Life and Background
Kathryn Bridget Moynahan was born on April 28, 1971, in Binghamton, New York. She is the daughter of Irish Americans Mary Bridget Moriarty, a former school teacher, and Edward Bradley Moynahan, a scientist and former administrator at the University of Massachusetts Amherst. Moynahan has described her family background as Irish-Catholic and grew up with an older brother, Andy, and a younger brother, Sean.
When she was around seven years old, the family moved to Longmeadow, Massachusetts, where she later attended Longmeadow High School. At Longmeadow, she was a standout athlete and captain of the girls’ soccer, basketball, and lacrosse teams. She graduated from high school in 1989 and has spoken about being a self-described tomboy during her childhood years.
Path to Acting
After graduating from high school, Moynahan pursued a modeling career even though she had not grown up reading fashion magazines. She accompanied a friend to a modeling audition in Springfield, Massachusetts, and was signed by an agency while her friend was not. She moved to New York City at age 18 and, a year later, began appearing in publications such as Vogue and Elle, including cover work for Vogue Paris and Glamour.
Knowing that modeling would not last forever, Moynahan began taking acting and art classes while continuing her commercial work in soaps and shampoos. She studied acting with Iris Klein, and in 1999 she made her television debut as Natasha in the HBO romantic comedy Sex and the City. The recurring role, which ran through the divorce of her character from Mr. Big, marked her first sustained screen presence and opened the door to feature-film work.
