The KBO League (Korean: KBO 리그), originally called the Korea Baseball Championship (Korean: 한국야구선수권대회; Romanization: Hanguk Yagu Seonsukkwon Daehoe), is the highest level league of baseball in South Korea. The KBO League was founded with six franchises in 1982, and has expanded to ten franchises. Nine of the ten franchises are named after the companies or business conglomerates which own them, while one sold their naming rights (Woori Heroes in 2008, Nexen Heroes from 2010 to 2018, and Kiwoom Heroes from 2019). The KBO League is the most popular sports league in South Korea. Kia Tigers (formerly Haitai Tigers) are the most successful team, having won 11 out of the 38 championships.

The inaugural franchises were:
- Haitai Tigers, based in Gwangju
- Lotte Giants, based in Busan
- MBC Chungyong, based in Seoul
- OB Bears, based in Daejeon
- Sammi Superstars, based in Incheon
- Samsung Lions, based in Daegu
In 1985, the Sammi Superstars became known as the Cheongbo Pintos. The next year, 1986, saw some major changes, with the OB Bears moving from Daejeon to share the Seoul's Jamsil Baseball Stadium with MBC Chungyong in Seoul. A new franchise, the Binggrae Eagles, joined to replace vacancy of Daejeon by OB's moving and expanding the league to seven franchises. 1988 saw the Cheongbo Pintos change ownership again, becoming the Pacific Dolphins. In 1990, MBC Chungyong became the LG Twins and an eighth franchise was added, the Ssangbangwool Raiders who represented the Jeollabuk-do region.
There was little change in the 1990s except for a few major sponsors: in 1993 the Binggrae Eagles became the Hanwha Eagles, in 1995 the Pacific Dolphins became the Hyundai Unicorns and the OB Bears in 1999 became the Doosan Bears. Bigger changes were affected in 2000 when the Hyundai Unicorns moved from Incheon to Suwon, and a new franchise, the SK Wyverns took their place in Incheon. The Ssangbangwool Raiders became defunct. In 2001, the Haitai Tigers became the Kia Tigers.
In 2008, the Hyundai Unicorns franchise was disbanded, re-founded as the Woori Heroes and moved to Mok-dong in Seoul. In 2010, the team's naming rights were sold to Nexen Tire and the team was renamed Nexen Heroes, until the end of the 2018 season, when its naming rights were sold to Kiwoom Securities.
Expansion resumed in the 2010s, with the addition of the NC Dinos, located in Changwon, which joined the league in 2013. It is the first team located in Changwon, the city having previously been the second home of the nearby Lotte Giants.
In 2015, the KT Wiz became the league's tenth franchise. They play their home games in Suwon, which had not had a team since the Hyundai Unicorns' disbandment.
Starting with the 2015 season, each team plays 144 games in the regular season, increased from 128 due to the addition of the KT Wiz to the league. Each team plays every other team 16 times.
KBO All-Star Game
In mid-July of every season, the best players participate in the KBO All-Star Game. The franchises participating are divided into two sets of teams: Dream All-Stars (Doosan, KT, Lotte, Samsung, and SK) and Nanum All-Stars (Kia, Hanwha, LG, NC and Kiwoom). The KBO All-star game does not determine home-field advantage in the KBO Korean Series.
The KBO League's season culminates in its championship series, known as the KBO Korean Series. Currently, the top five teams qualify for the post-season based on win/loss records. The lowest-qualifying teams face off in a step-ladder playoff system, where each winner then faces the next-highest team, culminating in the Korean Series against the top-ranked team.
- KBO Wild Card Game: fifth-place team vs. fourth-place team
- Fourth-place team starts the series with a 1–0 lead and advances with one win or a tie, while the fifth-place team must win twice to advance.
- KBO Semi-playoffs: KBO Wild Card Game winner vs. third-place team
- Best of five series.
- KBO Playoffs: KBO Semi-playoffs winner vs. second-place team
- Best of five series.
- KBO Korean Series: KBO Playoffs winner vs. first-place team
- Best of seven series.
Any playoff games ending in an official tie are replayed, thereby raising the possibility of a close series containing more than the scheduled five or seven games.
Traditionally, South Korean professional baseball games have a maximum number of extra innings before a game is declared an official tie. The KBO abolished this limit for the 2008 season, however it was reinstated in 2009, with a 12-innings limit imposed during regular season, 15-innings limit for playoff games. The league places a cap on the number of foreign players allowed on club rosters. The foreign player limit is set at three, increased from two players from 2014.
The designated hitter rule is universal in KBO.
