The R League (Korean: R리그), also known as the Korean Professional Football Reserve League, is the league for reserve teams of professional association football clubs in South Korea. The league started in 1990 with five reserve teams of K League member clubs: POSCO Atoms, Yukong Elephants, Daewoo Royals, Hyundai Horang-i and Lucky-Goldstar Hwangso. Pohang Steelworks won the inaugural title, finishing two point ahead of Yukong Elephants to lift the crown. But league was shortlived for only one year and reserve teams participated in semi-professional tournaments such as the National Football Championship.
