The 1902–03 season was Tottenham's seventh season as a fully professional club and the 20th year in existence. They competed in three leagues, the main being the Southern Football League along with the Western League and London League, along with the FA Cup.
Tottenham’s only success was in the London League where they went on to win the trophy. All seasons after this one only the Tottenham reserves competed in the London League. In the FA Cup they made it to the third round and were drawn at home to Aston Villa but were knocked out after the match finished 3–2 in Villa's favour.
