This is a list of various things that took place in 1966.
Significant events
January
- 7 - Lou Thesz loses the NWA World Heavyweight Championship to Gene Kiniski in the main event of a show in St. Louis. It is Thesz's last reign as NWA World Champion over a 29-year period, and he will be one of the final pre-World War II wrestlers to have held a specific major promotion world title (although not continuously) well into the Vietnam War-era. After losing several rematches, Thesz would continue to wrestle on a part-time basis and held his last significant championship -- the Universal Wrestling Association World Heavyweight Championship in Mexico -- in 1977.
September
- Alex Turk Promotions ceases operations following its September 3 event, citing increased competition from the American Wrestling Association, which had been holding events in Turk's stronghold of Winnipeg
