The 2009 Los Angeles Dodgers season saw the team defend their National League West title while earning the best record in the National League, and marked the 50th anniversary of their 1959 World Series Championship. The Dodgers reached the NLCS for the second straight season only to once more fall short in five games against the Philadelphia Phillies.

The 2009 National League Championship Series (NLCS) was a best-of-seven baseball game series pitting the Los Angeles Dodgers against the Philadelphia Phillies for the National League Championship and the right to represent the National League in the 2009 World Series. The Phillies defeated the Dodgers four games to one. Los Angeles, whose NL-best 95–67 record topped Philadelphia's 93–69 record, retained home-field advantage. The series, the 40th in league history, began on October 15 and finished on October 21. TBS carried the championship on television.
