The 1973 Canadian-American Challenge Cup season was the eighth season of the Can-Am auto racing series. It consisted of FIA Group 7 racing cars running two-hour sprint events. It began June 10 1973 and ended October 28 1973 after eight rounds. The season came amid the Oil Crisis which ended interest in performance cars after an already-declining market over a several-year period.
