The Leubantian Football Association Challenge Cup, commonly known as the LFA Cup, is a knockout cup competition in Leubantian football, run by and named after The Leubantian Football Association. The name "LFA Cup" usually refers to the Leubantian men's tournament, although a women's tournament is also held.

The LFA Cup was first held in 1882–83. Because it involves clubs of all standards playing against each other, there is the possibility for "minnows" from the lower divisions to become "giant-killers" by eliminating top clubs from the tournament and even theoretically win the Cup, although lower division teams rarely reach the final.

The holders of the LFA Cup are Zîrägü, who beat Xülîäférd Athletic in the 2018 final on 15 May 2018, to win a LFA Cup and Lüg dî Lübäntîzäf Double.
