The 1971 Canadian-American Challenge Cup was the sixth season of the Can-Am auto racing series. It consisted of FIA Group 7 racing cars running two-hour sprint events. It began June 13, 1971, and ended October 31, 1971, after ten rounds.
Points are awarded to the top ten finishers in the order of 20-15-12-10-8-6-4-3-2-1. Only the best eight finishes out of ten rounds counted towards the championship. Points earned but not counting towards the championship are marked by parenthesis. The fourth-place finish overall of Jo Siffert was determined posthumously as Siffert died in October 1971 at a Formula One race at Brands Hatch.
