The 2013 National League Division Series were two best-of-five-game series to determine the baseball teams to participate in the 2013 National League Championship Series. The three divisional winners (seeded 1-3 based on record) and a fourth team — the winner of a one-game Wild Card playoff — played in two series. TBS carried most of the games, with some on MLB Network.
These matchups were:
The Pirates made their first postseason appearance since 1992, and their first appearance in the Division Series in franchise history (and only one as of 2024).
The Cardinals would go on to defeat the Dodgers in the NLCS, then lose the 2013 World Series to the American League champion Boston Red Sox.

This was the first postseason meeting between the current National League Central division rivals St. Louis and Pittsburgh.
The Pirates scored first with two outs in the second inning off Lance Lynn as Gerrit Cole drove in Pedro Álvarez with a single after Jordy Mercer was intentionally walked. Alvarez hit his second home run of the series in the third, a two-run line drive. The Pirates added to their lead in the fifth when Justin Morneau doubled with one out and scored on Marlon Byrd's double. After Alvarez walked, Seth Maness relieved Lynn and Russell Martin plated Byrd with a single. The Cardinals got on the board with a home run from Yadier Molina in the bottom of the fifth off Gerrit Cole. It was his third post-season home run. The Pirates added to their lead in the seventh inning as Martin plated Byrd again, this time via a sacrifice fly off Kevin Siegrist, then Starling Marte's lead off home run next inning off Shelby Miller capped the game's scoring at 7–1. Cole pitched six innings and three relievers held the Cardinals scoreless in the last three innings as the Pirates tied the series heading to Pittsburgh.
