Darren Todd Thurston (born c. 1970) is a Canadian former animal rights activist. In July 2006, Thurston pleaded guilty to criminal conspiracy and related arson charges that occurred from 1996 through 2001 in Oregon and four other U.S. states, and which were claimed in the name of the Earth Liberation Front (ELF) and the Animal Liberation Front (ALF). The FBI arrested Thurston and 10 other members of a west coast-based animal rights and environmentalist organization that the FBI and media called "The Family." The arrests were made as part of the FBI's Operation Backfire.
