The 2011 National League Division Series (abbreviated NLDS) were two best-of-five playoffs comprising the opening round of the Major League Baseball postseason, played to determine the participating teams in the 2011 National League Championship Series. Three divisional winners and a fourth team—a wild card—played in two series. TBS televised all games in the United States (except Game 3 of the Brewers–Diamondbacks series, which aired on TNT due to scheduling conflicts with the ALDS). The regular season finished on September 28, with the National League playoffs beginning October 1.
