The 2010 National League Championship Series (NLCS) was a best-of-seven game Major League Baseball playoff series that pitted the winners of the 2010 National League Division Series—Philadelphia Phillies and San Francisco Giants—against each other for the National League Championship. The Giants won the series 4–2 and went on to win the 2010 World Series. The series, the 41st in league history, began on October 16 and ended on October 23. The Phillies had home field advantage as a result of their better regular-season record. The Phillies hosted Games 1, 2 and 6, while the Giants were at home for Games 3, 4 and 5.
