The 1966 Cotton Bowl (Dec.) was a college football postseason bowl game played by the SMU Mustangs and the Georgia Bulldogs in Dallas, Texas.The 1967 game was moved to Saturday, December 31, 1966, due to the Dallas Cowboys hosting the NFL Championship Game at the stadium on New Year's Day, the usual day for the Classic. Because January 1 was a Sunday, the Sugar, Orange, and Rose Bowls were played on Monday, January 2.

The #10 Mustangs (8–2) had won the Southwest Conference (SWC) championship (6–1) for the first time since 1948, led by fifth-year head coach Hayden Fry. They had won all five games that season at the Cotton Bowl, their home stadium through 1978. Fourth-ranked Georgia (9–1) had shared the Southeastern Conference (SEC) title (6–0) with Alabama, with only a one-point loss to Miami their only blemish. They were led by Vince Dooley, in his third season of 25 seasons as head coach of the Bulldogs, and were a seven-point favorite. Kickoff for the game was 1:30 p.m. CST and it was televised by CBS.
