The National Circuit configuration at Korea International Circuit in Yeongam delivers a mid-length layout between compact club circuits and the full 5.615-kilometer Grand Prix configuration at this facility that hosted Formula One from 2010-2013. The National designation serves Korean domestic championships requiring professional infrastructure without the intimidating distance of the full GP layout that achieved brief international prominence. This configuration bridges accessibility with legitimate championship challenge.

Operating the National configuration showcases Korea International Circuit's versatility in serving varied skill levels beyond its short-lived Formula One hosting period. The National layout provides appropriate challenge for Korean domestic racing series while maintaining FIA safety standards and comprehensive infrastructure. Korean climate creates distinct seasonal racing windows with the facility located in South Jeolla Province. The National circuit serves as the facility's intermediate option, allowing Korea International Circuit to accommodate varied event types from club racing to national championships at this modern Korean motorsport venue.
