Korean Series

The Korean Series is the final championship series of the KBO League. It has been held since the KBO League's first season in 1982 and is the final series of the post-season play-offs. From 2005 to 2013, the winner of the Korean Series went on to play in the Asia Series.

The teams finishing in third and fourth place in the regular season face each other in the first round of the play-offs. The winner of the first round faces the team that finished in second place during the regular season, and the winner of that round faces the team that finished in first place for the championship in the Korean Series. The Wild Card Game between the teams finishing in fourth and fifth place in the regular season was added to the KBO League postseason in 2015.

All championships are a best-of-seven playoff series between the league pennant winner and the winner of the second round of the play-offs. If the game ends in a tie, more games would be scheduled until any one of the teams wins four games.
