History

The arrondissement of Dieppe was created in 1800. At the January 2017 reorganisation of the arrondissements of Seine-Maritime, it received 12 communes from the arrondissement of Le Havre and four communes from the arrondissement of Rouen, and it lost four communes to the arrondissement of Rouen.

As a result of the reorganisation of the cantons of France which came into effect in 2015, the borders of the cantons are no longer related to the borders of the arrondissements. The cantons of the arrondissement of Dieppe were, as of January 2015:
