Jung Jae-kun (born 23 July 1969) is a South Korean retired basketball player. His playing career spanned thirteen years and coincided with the founding of the all-professional Korean Basketball League. Possessing the ability and skillset to play as either a center or a forward, he is credited with paving the way for the "center-forward" swingman to succeed in domestic basketball during an era where such players were often viewed as being strategically difficult to fit into the team's tactics.
