The parishes of Jersey are the civil and religious administrative districts of Jersey in the Channel Islands. All have access to the sea and share a name with their ancient parish churches. The parishes and roles within them are based on ancient Jersey law, drawing from the Norman customary law system. As such, many of the parish roles and structures have often been ill-defined.

Jèrriais is a Romance language and the traditional language of the Jersey people. It is a form of the Norman language spoken in Jersey, an island in the Channel Islands archipelago off the coast of France. Its closest relatives are the other Norman languages, such as Guernésiais, spoken in neighbouring Guernsey, and the other langues d'oïl.
