Rob Lowe (born March 17, 1964 in Charlottesville, Virginia, USA) is an American actor who was a member of the Brat Pack.

Rob Lowe became famous after appearing in a string of popular movies that included other members of the brat pack, the most notable being St. Elmo's Fire. Lowe and his brother Chad Lowe grew up on the Westside of Los Angeles and attended Santa Monica High School, where one of their classmates was fellow brat-packer, Emilio Estevez. Today, Lowe makes his home with his wife and children in Montecito, CA.

Lowe gained notoriety in 1988 after a video of him having sex with two women, one of whom was underage, became public. He had met the women at a bar while in Atlanta attending the 1988 Democratic National Convention, and later said that while he didn't know one was underage, it was reasonable to assume that someone in a bar was of legal age. Lowe was sentenced to twenty hours of community service.

He is perhaps best known for playing Sam Seaborn in the television show The West Wing, a role which was his from 1999 - 2003. When the show premiered, Lowe's character was to be much more important. But the extremely talented cast — including Allison Janney, Richard Schiff, Stockard Channing, Bradley Whitford and Martin Sheen (who was only supposed to be a guest star) — soon made the show into the hottest ensemble cast on TV, and Sam Seaborn became possibly the character with the least screen time. Lowe left the show in a highly publicized exit during the fourth season. His exit was quickly followed by that of series creator and writer Aaron Sorkin, and director Thomas Schlamme - a move which saw the show's style change greatly, to mixed reactions from fans.

After leaving, he was star and executive producer of a failed NBC drama The Lyon's Den (2003). In 2004, he tried again in a series entitled dr. vegas, but it also was cancelled.

In the fall of 2005, he will star as Lieutenant Daniel Kaffee in a London West End production of Aaron Sorkin's play A Few Good Men.
