Norval Eugene Turner (born May 17, 1952) is the head coach for the National Football League's San Diego Chargers. He also has served as head coach of the Washington Redskins and the Oakland Raiders, and as offensive coordinator for the Dallas Cowboys, San Diego Chargers, Miami Dolphins, and San Francisco 49ers. His explosive offense, built around a strong ground attack and the ability to strike fast via the deep pass, is referred to as "Norv-West Air", a play on the name of an airline with a similar name. He is the brother of former University of Illinois head football coach and former Chicago Bears offensive coordinator Ron Turner.

Turner was a student at Alhambra High School in Martinez, California. In football, he played quarterback and safety. He graduated from Alhambra in 1970 and then attended the University of Oregon, where he was a back-up quarterback to former San Diego Charger and Hall of Famer Dan Fouts.

After serving as a graduate assistant coach at Oregon, Turner was an assistant coach for the USC Trojans from 1976 to 1984. From 1985 to 1990, he was an assistant with the Los Angeles Rams. In the January 2008 issue of San Diego Magazine he was chosen as one of the "50 People to Watch in 2008."
