The 2002 National League Championship Series (NLCS) was a Major League Baseball playoff series played from October 9 to 14 to determine the champion of the National League, between the Central Division champion St. Louis Cardinals and the wild-card qualifying San Francisco Giants. It was a rematch of the 1987 NLCS, in which the Cardinals defeated the Giants in seven games. The Cardinals, by virtue of being a division winner, had the home field advantage. The Giants won the series in five games but were defeated by the Anaheim Angels in seven games in the World Series.
