The 2002 Norwich Union League season was a 45 over English county cricket competition; colloquially known as the Sunday League, it featured many mid-week floodlit matches. It was contested through two divisions: Division One and Division Two. Each team played all the others in their division both home and away. The top three teams from Division Two were promoted to the first division for the 2002 season, while the bottom three sides from Division One were relegated. All eighteen counties retained the nicknames from the previous season.^[3]

Glamorgan Dragons won the League for the second time. Somerset Sabres, Durham Dynamos and Nottinghamshire Outlaws were relegated from Division One, while Gloucestershire Gladiators, Surrey Lions and Essex Eagles were promoted from Division Two.
