The 2018–19 FA Women's National League Plate is the fifth running of the competition, which began in 2014.
All 72 National League clubs were included in the determining round draw.
St Nicholas withdrew from the competition before playing a match, meaning 36 teams progressed in the Cup and 35 were entered in the Plate.
West Ham United were the reigning champions, having defeated Luton Town 5–0 in the 2017–18 final,[2] but did not defend their title after obtaining a licence to the FA Women's Super League.
Due to there being 35 teams in the competition, three first round matches are played to eliminate three teams allowing a full single-elimination knockout tournament to take place.
