The 2015 Singapore League Cup (known as the TNP League Cup for sponsorship reasons) was the ninth season of Singapore's premier club football tournament organised by the Football Association of Singapore. 
DPMM FC were the defending champions, having won their third trophy the previous year. Albirex Niigata (S) were the eventual winners after defeating 2013 champions Balestier Khalsa 2–1 in the finals.
Unlike the previous three tournaments held in 2012, 2013 and 2014, the League Cup Plate Competition between the third-placing teams in each group after the group stages were cancelled from 2015 onward.
