The 2017–18 Toto Cup Leumit is the 28th season of the second tier League Cup (as a separate competition) since its introduction. It is divided into two stages. First, sixteen Liga Leumit teams were divided into four regionalized groups, with the winners and runners-up advanced to the quarter-finals. Quarter-finals, semi-finals and the final are due to be held as one-legged matches. The defending cup holders, Maccabi Sha'arayim, are not competing in this edition, as the club was relegated to Liga Alef at the end of the previous season.
