The 2015–16 Toto Cup Leumit was the 26th season of the second tier League Cup (as a separate competition) since its introduction. It was held in two stages. First, sixteen Liga Leumit teams were divided into four regionalized groups, from which the winners and runners-up advanced to the quarter-finals. Quarter-finals, semi-finals and the final were then played as one-legged matches. The defending cup holders were Hapoel Bnei Lod, having won the cup on its previous edition. In the final, played on 15 December 2015, Hapoel Ashkelon defeated F.C. Ashdod 1–0.
