The 2002–03 FA Cup qualifying rounds opened the 122nd season of competition in England for 'The Football Association Challenge Cup' (FA Cup), the world's oldest association football single knockout competition. A total of 624 clubs were accepted for the competition, up 28 from the previous season’s 596.

The large number of clubs entering the tournament from lower down (levels 5 through 10) in the English football pyramid meant that the competition started with six rounds of preliminary (2) and qualifying (4) knockouts for these non-League teams. South Western Football League was the only level 10 league represented in the Cup, three clubs from the South Western Football League were the lowest-ranked clubs in competition. The 32 winning teams from fourth round qualifying progressed to the First round proper, where League teams tiered at levels 3 and 4 entered the competition.
