The 2002–03 Divizia B was the 63rd season of the second tier of the Romanian football league system. The format has been maintained to two series, each of them having 16 teams. At the end of the season, the winners of the series promoted to Divizia A and the last two places from both series relegated to Divizia C. A promotion play-off was played between the 13th and 14th-placed in the Divizia A and the runners-up of the Divizia B series.
