Xander Berkeley (born December 16, 1955) is a well-known American actor, who, despite having had few leading roles, has appeared in more than 80 motion pictures.

A native of Brooklyn, Berkeley began playing minor roles in 1981, with early appearances in M*A*S*H, Cagney & Lacey, Remington Steele, Miami Vice, Moonlighting and The A-Team. Although not becoming a household name, Berkeley's face was increasingly recognizable into the 1990s. His later television guest roles included The X-Files, CSI, ER and Law & Order.

On the big screen, Berkeley appeared in Terminator 2: Judgment Day, Candyman, Apollo 13, Leaving Las Vegas, Gattaca, Air Force One, Spawn, Amistad, Shanghai Noon, and Timecode. Several of his earlier roles were in films by director Alex Cox. Most of his roles have been unsympathetic characters.

In 2001, Berkeley became a recurring guest star on 24 as George Mason, a head honcho for the Counter Terrorist Unit. His character, initially presumed evil by other characters and the fans, was revealed to be one of the good guys and became a main character in season 2, only to meet an untimely (but heroic) end. However, the show did give Berkeley the chance to meet his future wife Sarah Clarke, who played turncoat agent, and much-loved villainess Nina Myers for the first three seasons of the show.

Berkeley has also provided voices for animated series such as Aaahh!!! Real Monsters and Gargoyles.
