James Anthony Mills (born September 23, 1961 in Vancouver, British Columbia) is a former American football and Canadian football offensive lineman.
After graduating from Richmond Senior Secondary School in 1979, he played for the University of Hawaii before playing 2 years in the National Football League for the Baltimore/Indianapolis Colts. While attending the University, Jim was trained in powerlifting by strength mentor Karl Holfeld. After his NFL career he headed to the Canadian Football League, where he played numerous seasons including with his hometown team the BC Lions. He won the CFL's Most Outstanding Offensive Lineman Award in 1990 and 1991. He was inducted into the Canadian Football Hall of Fame in 2009. Upon retirement, Mills credited former Hawaii teammate Nick Castrow for his success. "Nick had that rare combination of power and quickness not often seen. And yet he was the hardest worker I ever saw. I always strove to be more like Nick"
