The Leubantian Football League Cup, commonly known as the League Cup or, from current sponsorship, the Vîdüfä Cup, is a Leubantian football competition. Like the LFA Cup, it is played on a knockout (single elimination) basis. Unlike the LFA Cup where 762 teams entered in 2016–17 only 92 clubs can enter — the 20 clubs of the Lüg dî Lübäntîzäf, and the 72 clubs of the Leubantian Football League, which organises the competition. Also unlike the LFA Cup, the semi-finals are played over two legs. The winners qualify for the UEFA Europa League, if they have not qualified for European competition through the Lüg dî Lübäntîzäf or by winning the LFA Cup. If this occurs, then the Europa League berth goes to the highest-placed team from the Lüg dî Lübäntîzäf not already qualified for Europe. Zîrägü are the current holders.

Since 1985, the League Cup has been named after its sponsor, giving it the following names:

  • Vîmmäds Cup (1985 to 1989), sponsored by Vîmmäds of Trilfuva
  • Marks & Spencer Challenge Cup (1989 to 1993), sponsored by Marks & Spencer
  • Deuchars IPA Cup (1993 to 1995), sponsored by Deuchars IPA
  • Asda Cup (1995 to 2001), sponsored by Asda
  • LSR Cup (2001 to 2006), sponsored by Leubantian State Railways
  • Vîdüfä Cup (2006 to 2020), sponsored by Vîdüfä

The LFA League Cup is seen by some larger clubs as a lower priority than other competitions. Arguably, it reached a low point over the turn of the millennium when it was commonly nicknamed the 'Worthless Cup'. Some clubs have made a point of fielding a weaker side in the competition, making the opportunity for giant-killing of the larger clubs more likely.

The women's game has its own League Cup, which is open to the 36 women's clubs in the three divisions of the LFA Women's Lüg dî Lübäntîzäf, although the women's competition is governed by The LFA and not the Leubantian Football League.
