The 1966 Major League Baseball season was contested from April 11 to October 9, 1966. The Braves played their inaugural season in Atlanta, following their relocation from Milwaukee. Three teams played the 1966 season in new stadiums. On April 12, the Braves ushered in Atlanta–Fulton County Stadium with the Pittsburgh Pirates taking a 3–2 win in 13 innings. One week later, Anaheim Stadium opened with the California Angels losing to the Chicago White Sox, 3–1 in the Angels' debut following their move from Los Angeles to nearby Orange County. On May 8, the St. Louis Cardinals closed out old Sportsman's Park/Busch Stadium I with a 10–5 loss to the San Francisco Giants before opening the new Busch Memorial Stadium four days later with a 4–3 win in 12 innings over the Atlanta Braves. In the World Series the Baltimore Orioles defeated the Los Angeles Dodgers four games to zero.

For the first time, NBC became exclusive national TV broadcaster of MLB. The network replaced ABC as the holder of the Games of the Week package. The New York Yankees and Philadelphia Phillies, which had instead sold their TV rights to CBS in prior seasons, also joined NBC's package. The new package under NBC called for 28 games, as compared to the 123 combined among three networks during the 1960s. NBC also continued to air the All-Star Game and World Series.
