The 2015 National League Division Series were two best-of-five-game series to determine the participating teams in the 2015 National League Championship Series. The three divisional winners (seeded 1-3) and a fourth team—the winner of a one-game Wild Card playoff— played in two series. TBS carried all the games in the United States, with Sportsnet simulcasting TBS coverage for Canada. The Division Series began on October 9 and concluded on October 15. The Los Angeles Dodgers and St. Louis Cardinals had home field advantage in this round of the playoffs.

These matchups were:

The higher seeded team in each series hosts Games 1, 2, and 5 (if necessary), and the lower seeded team hosts Games 3 and 4 (if necessary).

The Mets and the Dodgers met for the third time in postseason play, having split the first two meetings (Dodgers won 4–3 in the 1988 NLCS; Mets won 3–0 in the 2006 NLDS). This was the third overall postseason meeting between the Cubs and Cardinals, with the two having met in the 1885 and 1886 World Series, and their first since the Cardinals joined the National League in 1892.

Chicago won the series, 3–1.

New York won the series, 3–2.

The St. Louis Cardinals shut-out the rival Chicago Cubs 4–0 behind John Lackey's 7⅓ shutout innings in the first meeting between the two in the playoffs. Lackey pitched into the sixth inning with a no-hitter before the Cubs' Addison Russell singled in the seventh. The Cardinals scored first when Matt Holliday hit a RBI single in the first. Lackey and Jon Lester, pitched well as neither team scored again until the eighth inning, when Thomas Pham and Stephen Piscotty homered for the Cardinals to increase the lead to 4–0. The Cubs attempted a comeback in the ninth inning, but the Cardinals secured the victory when Kris Bryant struck out with runners on first and third for the final out of the game.
