The 2013 Pittsburgh Pirates season was the franchise's 127th season as a member of the National League, 132nd season overall, and 13th season at PNC Park. The regular season began at home with a loss against the Chicago Cubs on April 1 and ended with a win at Great American Ball Park against the Cincinnati Reds on September 29. In their first winning season since 1992, the Pirates finished in second place in the National League Central with 94 wins and 68 losses.

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 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.
