The McLaren M6A was a Group 7 prototype race car designed and developed by driver Bruce McLaren, and built by his Bruce McLaren Motor Racing team for their entry in 1967 Can-Am season. As a replacement for the team's M1Bs from 1966, the Chevrolet-powered M6A's improved design earned Bruce McLaren and his team their first of multiple Can-Am championships. After the M6As were replaced by the M8A in preparation for 1968, McLaren and technical partner Trojan–Tauranac Racing developed the M6B which was sold to customers for use in Can-Am as well as other racing series.

The 1967 Canadian-American Challenge Cup was the second season of the Can-Am auto racing series. It involved FIA Group 7 racing cars running two-hour sprint events. It began September 3, 1967, and ended November 12, 1967, after six rounds.
