The 2007 National League Championship Series (NLCS), the final round of the 2007 National League playoffs, began on October 11 and ended on October 15. It was a best-of-seven series, with the West Division champion Arizona Diamondbacks facing the divisional rival wild card winner Colorado Rockies. The Rockies swept the series in four games to win their first ever pennant, extending a 17–1 run to 21–1 in the process. The Rockies won the opportunity to play the American League champion Boston Red Sox in the 2007 World Series, where they were swept 4-0. Colorado's NLCS sweep was only the second NLCS sweep since the seven-game format was adopted in 1985, with the first being the Atlanta Braves' sweep in 1995.
The Rockies had swept the Philadelphia Phillies in three games in the NL Division Series, while the Diamondbacks had swept the Chicago Cubs. The Diamondbacks had home-field advantage due to winning the division. The series marked the first time the Rockies ever advanced to the NLCS and the second time for the Diamondbacks, in the first postseason matchup between the two teams; the Rockies' only prior postseason appearance was in 1995. It was the first time that two West Division teams had ever met in the NLCS, only the second to feature expansion franchises (the first being 1986) and the first of only two postseason meetings of any kind between teams that joined MLB in the 1990s (the other meeting being the 2017 NL Wild Card Game between the same two clubs).
The series was telecast on TBS, the first time a League Championship Series was ever shown exclusively on a cable network.
