The 1902–03 Football League season was Small Heath Football Club's 11th in the Football League and their 8th in the Second Division. Having been relegated in 1901–02, they reached the top two positions by mid-November and remained there for the rest of the season, finishing as runners-up in the 18-team league, so were promoted back to the First Division at the first attempt. They also took part in the 1902–03 FA Cup, entering at the first round proper (round of 32) and losing in that round to Derby County. In locally organised competition, they lost to Aston Villa in the first round of the Birmingham Senior Cup after two replays.
