The 1962 Major League Baseball season was contested from April 9 to October 16, 1962. The National League (NL) added two teams via expansion, the Houston Colt .45s and New York Mets. This marked the return of the NL to New York City after a four-year absence, although the Mets would lose 120 games and finish in last place. All major league teams now played 162-game schedules, which had been adopted by the American League (AL) the prior season, with each team facing the nine other clubs in the same league 18 times during the season.

The 1962 National League tie-breaker series was a best-of-three playoff series that extended Major League Baseball's (MLB) 1962 regular season to determine the winner of the National League (NL) pennant. The games were played from October 1 to 3, 1962, between the Los Angeles Dodgers and the San Francisco Giants. The Giants won the series, two games to one. The first game took place at Candlestick Park and the second and third were played at Dodger Stadium. The tie-breaker series was necessary after both teams finished the season with identical win–loss records of 101–61. The Dodgers won a coin flip late in the season, which gave them home field advantage. The series was broadcast nationally by NBC television, with Bob Wolff, George Kell, and Joe Garagiola announcing, and NBC Radio, with Al Helfer and George Kell announcing.
