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.
The league began play in 1982 with six teams. There were no changes to the league through 1985, except for the Sammi Superstars being renamed as the Chungbo Pintos that season.
