The 2015 KBO League season was the 34th season in the history of the Korea Professional Baseball league.
Due to the addition of the KT Wiz into the KBO, the 2015 KBO league schedule was increased to each team playing 144 games during the regular season (each team had played 128 games during the 2014 regular season), with each team playing each other 16 times.[1]
In July, the best players participated in the 2015 KBO All-Star Game. The participating franchises were divided into two regions, the Dream All-Stars (Samsung Lions, Doosan Bears, Lotte Giants, SK Wyverns, KT Wiz) and Nanum All-Stars (Kia Tigers, Hanwha Eagles, LG Twins, Nexen Heroes, NC Dinos). The Korean All-Star Game did not determine home-field advantage in the Korean Series. The All-Star Game was played on 18 July 2015 at the Suwon Baseball Stadium and won by the Dream All-Stars 6–3.
2015 KBO League season culminated in its championship series, known as the Korean Series. The Semi-Playoff format was tweaked. Previously, the top four teams after the end of the regular season qualified for the postseason, but in 2015, the top five teams qualified for the postseason. The team with the best record gained a direct entry into the Korean Series, while the other four teams competed for the remaining place in a step-ladder playoff system. Starting in 2015, the fourth-place and the fifth-place teams played in a "Wildcard" game.[2]

Each team could have signed up to three foreign players. Due to the high proportion of pitchers signed in previous years, beginning in 2014 the league mandated that at least one of the foreign players must be a position player.
