The Prime League was the reserve and youth team football league of Singapore's S.League. Teams involved in the league are primarily made up of youth players from the S.League clubs. The Prime League was founded in 1997. S.League clubs are required to participate, and clubs who do not play at S.League level are also eligible to enter. In 2018, the Prime League was abolished, with the National Football League (NFL) installed as the second-tier competition.
