Jason O'Mara is an Irish actor.


O'Mara was born in Dublin, Ireland, on August 6, 1972, to Veronica and Stephen O'Mara; he has one brother named Stephen and one sister named Rebecca. In his early years, he loved to play rugby and had little interest in acting. However, this changed when he had to be sidelined after suffering an injury. As a result, O'Mara decided to try out for a school play, which got him hooked on acting as a career. He subsequently started working in local theater. His early theater credits in London and Dublin include appearances on The Jew of Malta, Popcorn, The Homecoming, and Bash. For his role in Bash, O'Mara was nominated for Best Supporting Actor in 2002 at the Irish Theatre Awards.

O'Mara later moved on to starring in television, starting with BBC. His television work with BBC included Playing the Field, Berkeley Square, High Stakes, and Monarch of the Glen. In 2001, O'Mara made his U.S. television debut by starring in Steven Spielberg's Band of Brothers, which was produced for and aired on HBO. He then moved to Los Angeles, California, and soon afterwards, made the pilot Eastwick for FOX; however, it wasn't picked up. Afterwards, he was offered roles on two CBS-produced series, The Agency and Presidio Med. He chose to star in The Agency, in which he portrayed the character of A.B. Stiles for the show's second season.

O'Mara also made guest-star appearances on several series. Such shows include CSI: Miami, The Closer, Men in Trees, and Criminal Minds. He struck a partnership with ABC and Touchstone and has been working for both companies for the past few years. He created three more pilots, consisting of Countdown, Drift, and Marlowe. O'Mara also created a TV series titled In Justice, which aired as a mid-season replacement during the 2006-07 season. In his personal life, Jason met his wife, American actress Paige Turco, while they were both starring on The Agency. They fell in love, got married in 2003, and now have one son named David. They have residences in Los Angeles, as well as Connecticut and New York.
