Chun Ju-do (Korean: 전주도; Hanja: 全周都; born January 25, 1964, in Gangwon Province, South Korea) is a former boxer from South Korea.

Chun fought for the inaugural IBF super flyweight title in 1983, winning with a 5th-round TKO over Ken Kasugai in Osaka, Japan.

He became the youngest Korean boxer to win a world title, at 19 years and 10 months old, and this record remains unbroken today.

He defended the belt five times before losing it to future 3-time IBF super flyweight champion Ellyas Pical in Jakarta, Indonesia in 1985.
