2019–20 FA Women's National League Cup

The 2019–20 FA Women's National League Cup is the 29th running of the competition, which began in 1991. It is the major League Cup competition run by the FA Women's National League, and for the sixth season it is being run in conjunction with their secondary League Cup competition, the National League Plate.

Seventy of the seventy-one National League clubs entered at the competition in the Determining round, with the winners continuing into the competition proper and the losers going into the National League Plate tournament. The only exception were Larkhall Athletic who were granted a bye into the first round proper of the cup. The previous two tournaments were both won by Blackburn Rovers, but after winning promotion to the FA Women's Championship in the summer of 2019 they did not take part in the competition this season.

Due to the COVID-19 pandemic, the final was not held and no winners were named.
