卡朗唐（法语：Carentan）是法国下诺曼底大区芒什省的一个镇，位于科唐坦半岛。

Carentan (pronounced: [kaʁɛ̃tɑ̃]) is a small rural town near the north-eastern base of the French Cotentin Peninsula in Normandy in north-western France near the port city of Cherbourg, with a population somewhat over 6,000. It is a former commune in the Manche department. On 1 January 2016, it was merged into the new commune of Carentan-les-Marais. The town was a strategic early goal of the World War II landings as capturing the town was necessary to link the lodgements at Utah and Omaha beaches which were divided by the Douve River estuary (Nearby fields were flooded by the Germans up to the town's outskirts). The town was also needed as an intermediate staging position for the capture of the cities of Cherbourg and Octeville, with the critically important port facilities in Cherbourg.
