The Korean Series is the final championship series of the KBO League. It has been held since the KBO League's first season in and is the final series of the post-season play-offs. From to 2013, the winner of the Korean Series went on to play in the Asia Series.
The teams finishing in fourth and fifth place in the regular season face each other in the wild card game, which was added to the KBO League postseason in 2015.[1] The winner of the wild card game faces the team that finished in third place during the regular season in the first round of the play-offs, with the winner then facing the team that finished in second place during the regular season in the second round of the play-offs. The winner of that round faces the team that finished in first place for the championship in the Korean Series.
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. The series follow a 2–2–3 format since 2022; the first two games and the last three games, if necessary, are played at the home venue of the league pennant winner, while the third and fourth games are played at the home of the winner of the second round. If the game ends in a tie, more games would be scheduled until any one of the teams wins four games.
