This is a list of KBO League seasons, providing the final ranking of teams in the KBO League at the end of each season, based on the final regular-season standings plus postseason play including the Korea Series. Sections below are divided based on the number of teams in the league and the season format:
From 1982 to 1988, the regular season was divided into two — a spring season and a fall season — with a first-half pennant winner and a latter-half pennant winner. In 1999–2000, the KBO had two divisions of four teams each — the Dream League and the Magic League. From 1989 to 1998, and from 2001 onward, the KBO featured a single division.
