The 2002–03 Regionalliga season was the ninth season of the Regionalliga at tier three (III) of the German football league system.

The Regionalliga was split into two divisions, the Regionalliga Nord and the Regionalliga Süd. The league champions, Erzgebirge Aue and SpVgg Unterhaching, and the runners-up in both divisions, VfL Osnabrück and Jahn Regensburg, were promoted to the 2003–04 2. Bundesliga.

Teams
SV Babelsberg 03, 1. FC Saarbrücken, 1. FC Schweinfurt 05 and SpVgg Unterhaching came down from the 2001–02 2. Bundesliga, replacing VfB Lübeck, Eintracht Braunschweig, Wacker Burghausen and Eintracht Trier.

Regionalliga Süd
Five teams were due to be relegated, but Stuttgarter Kickers and Sportfreunde Siegen were reprieved because two of the relegated teams from the 2. Bundesliga, SSV Reutlingen and SV Waldhof Mannheim, could not achieve a Regionalliga license, and dropped another level, to the Oberliga.
