Peter Killian Gallagher (born August 19, 1955) is an American actor, musician and writer. Since 1980, Gallagher has played roles in numerous Hollywood films.

He currently appears in a recurring role on the USA Network drama Covert Affairs, as CIA Clandestine Services Director Arthur Campbell.
Early life 
Gallagher was born in New York City, New York. His mother, Mary Ann (née O'Shea), was a bacteriologist, and his father, Thomas Francis Gallagher II, was an advertising executive. He is of Irish Catholic background and was raised in Armonk, New York where he graduated from Byram Hills High School. Gallagher graduated from Tufts University, where he had been active in theater, appearing in such shows as Stephen Sondheim's Company and singing with the all-male a cappella group the Beelzebubs.
Gallagher's debut film performance was as one of the co-stars in the 1980 film, The Idolmaker.
Gallagher appeared on Broadway with Glenn Close in Tom Stoppard's The Real Thing, but first achieved fame for his role in Steven Soderbergh's Sex, Lies, and Videotape (1989). He also starred as Sky Masterson in the 1992 Broadway Revival of Guys and Dolls.
Gallagher played a potential career threat to Tim Robbins' studio executive in The Player (1992); the comatose fiancé of Sandra Bullock in While You Were Sleeping (1995); a real estate salesman having an affair with Annette Bening in American Beauty (1999); a media executive in Mr. Deeds (2002); and a political reporter exposing media ethics during a presidential debate in The Last Debate.
From 2003 to 2007, Gallagher starred as Sandy Cohen, a Jewish public defender and corporate lawyer, on the Fox television show The O.C.. He hosts an annual award ceremony named "The Sandy Cohen Awards" or The Sandys, which, in honor of his character on The O.C., gives a scholarship to a law school student at UC Berkeley who wants to become a public defender.
Gallagher released an album entitled 7 Days in Memphis in 2005, on the Sony BMG label. This includes a studio recording of his performance of "Don't Give Up On Me" (originally by Solomon Burke), which was featured in an episode of The O.C. He also has a video for his single "Still I Long For Your Kiss", in which he starred with his TV-wife Kelly Rowan.
In 2005, Gallagher received the P.T. Barnum Award from Tufts University for his exceptional work in the field of media and entertainment. In 2007, Gallagher received the "Light on the Hill" award at Tufts University. The award is given to notable alumni from Tufts who have demonstrated ambition, achievement, and active citizenship.
