The 2017 National League Championship Series was a best-of-seven playoff pitting the Los Angeles Dodgers against the defending World Series champion Chicago Cubs for the National League pennant and the right to play in the 2017 World Series. The series was a rematch of the 2016 NLCS, which Chicago won four games to two en route to their first World Series victory since 1908. This was just the 10th time two teams have met in at least two straight League Championship Series, which have existed since divisional play began in 1969. The Dodgers beat the Cubs in five games to win the NL pennant for the first time in 29 years, their last one in 1988.
