Fred Perry and Dorothy Round were the defending champions, but Perry was ineligible to compete after turning professional at the end of the 1936 season. Round partnered with Don Butler but lost in the third round to Don Budge and Alice Marble.
Budge and Marble defeated Yvon Petra and Simonne Mathieu in the final, 6–4, 6–1 to win the mixed doubles tennis title at the 1937 Wimbledon Championships.[1][2]
