The 2018–19 FA Trophy (known for sponsorship reasons as the Buildbase FA Trophy) is the 50th season of the FA Trophy, an annual football competition for teams at levels 5–8 of the English National League System.
One team at Level 8 did not enter (Guernsey). This was the first year to have an extra preliminary round, due to the increase from 72 to 88 teams in the Level 7 leagues.
Following their victory over Weymouth, Ramsbottom United are the lowest-ranked team still in the competition, and the only team left from the eighth tier of English football.
