The 2014 MLS Cup Playoffs was the nineteenth post-season tournament culminating the Major League Soccer regular season. The tournament began in late October and culminated on December 7, 2014 with MLS Cup 2014, the nineteenth league championship for MLS. The 2014 playoffs was the first time that the away goals rule was applied to the home-and-away, aggregate-goal series. The first series impacted by the rule was a Western Conference semifinal that saw the Seattle Sounders advance past FC Dallas when the first match (held in Dallas) ended 1–1 and the second (held in Seattle) ended 0–0.
