James Duke Mason (born April 27, 1992) is an American writer, activist and city official in West Hollywood, California. The only child of singer Belinda Carlisle and film producer Morgan Mason, he is also the only grandchild of the late British actor James Mason and his wife, media personality Pamela Mason.
Born in Los Angeles, Mason moved to Europe with his parents as a child. Mason is openly gay and came out to his family and friends at the age of 14 in 2006. After graduating from Mougins School, an international school in the south of France in July 2010, Mason moved back to the U.S. to study political science at California Lutheran University. After a year he moved to West Hollywood, California to pursue his passion for grassroots advocacy.
Mason was appointed to serve as a Page in the United States House of Representatives during the summer of 2008. He had a small acting role in the film "What Happens Next", which screened as part of the Hollywood Film Festival. In 2010, The Advocate listed Mason as one of the most influential young LGBT Americans in their "Forty Under 40" issue. He was named in OUT magazine's 2011 "Out 100" issue as one of the 100 most influential LGBT people in the world. He has appeared on TV shows such as Dr. Phil, Nancy Grace, and Politicking with Larry King to discuss LGBTQ issues. He served as an official surrogate for the campaigns of Barack Obama in the 2012 U.S. Presidential Election and Hillary Clinton in the 2016 U.S. Presidential Election. He served on the Board of Directors of Outfest from January 2012 to January 2015, making him the youngest Board Member in the organization's history.
