Robert Hepler Lowe (; born March 17, 1964) is an American actor, producer, and director. He is the recipient of two Screen Actors Guild Awards and has been nominated for six Golden Globes Awards and a Primetime Emmy Award.
Lowe made his acting debut at the age of 15 with ABC's short-lived sitcom A New Kind of Family (1979–1980). Following numerous television roles in the early 1980s, he came to prominence as a teen idol and member of the Brat Pack with roles in films like The Outsiders (1983), Class (1983), The Hotel New Hampshire (1984), Oxford Blues (1984), St. Elmo's Fire (1985), About Last Night... (1986), and Square Dance (1987). The success of these films established him as a Hollywood star.
Following a 1988 sex tape scandal, Lowe's public image and film career declined. By the turn of the millennium, his career saw a resurgence when he ventured back into television, making his breakthrough as Sam Seaborn on the NBC political drama The West Wing (1999–2003), for which he received nominations for a Primetime Emmy Award and two Golden Globe Awards. His other television roles include Robert McCallister on the ABC drama Brothers & Sisters (2006–2010), Chris Traeger on the NBC sitcom Parks and Recreation (2010–2014, 2015), Ethan Willis on the CBS medical drama Code Black (2015–2018), and the Fox drama 9-1-1: Lone Star (2020–present) as Owen Strand. In 2018, he made his directorial debut with the television film The Bad Seed, a remake of the 1956 film of the same name.
