The NIFL Reserve League is the successor to the Irish League B Division Section 2 which was formed in 1977, when the B Division split into two sections: Section 1 for intermediate clubs and the other for the reserve teams of senior clubs. Since the foundation of the B Division in 1951, these two categories of teams had competed together. In 1999, Section 1 of the B Division was renamed the Irish League Second Division and Section 2 became the Irish League Reserve League. In 2003, on the formation of the Irish Premier League, the IFA took direct control and the league was renamed the IFA Reserve League. In 2013, the Northern Ireland Football League took over, and the league was again renamed, to the NIFL Reserve League.
