Gavin George Harrison (Born 29 December 1970) is an Australian former actor, producer, photographer, electronic music composer and a creative innovator who lives in Los Angeles.

Motivated at a young age, Harrison developed the skills and passion for his craft thanks to the encouragement of his mother, a fellow artist, and creative spirit. Her support was integral in Harrison's early projects which included working on a film in Sweden and lighting design for the 5th annual International Contemporary Dance Convention in Hong Kong. Based on his work and aptitude test, Harrison was accepted into the Film & TV program at KvB College of Visual Communication at age 15. Harrison graduated with Distinction from the Film and Television course and received awards for "Most Outstanding Student" and "Best Editor".

Acting came naturally to Harrison and he quickly landed roles in Home and Away (1988), playing the resident rebel "Revhead" and as Gerard Kennedy's holographic son in the U.S. production of the TV series Mission: Impossible (1988). After multiple guest-starring and recurring roles on Australian television including GP and Family and Friends (1990), Harrison landed his first major role playing a cyclist named Hugo Strzelecki on the hit Australian drama A Country Practice (1981).

After a long engagement with A Country Practice, Harrison teamed up with a manager in Los Angeles thus launching his career in the United States. He appeared in several shows with re-occurring roles including Bafta Nominated BBC mini-series Signs and Wonders (1995), series cast member on NBC's Amazing Grace (1995), HBO film Public Enemies (1996), CBS' Diagnosis Murder (1993), 20th Century Fox's Chicago Hope (1994), and Exposé (2000).
