Mouzeil (French pronunciation: [muzɛj]; Breton: Mouzel) is a commune in the Loire-Atlantique department in the Pays de la Loire in western France.

Its neighboring communities are (counter-clockwise) Ligné to the south-west, Couffé, Mésanger, Teillé, Trans-sur-Erdre and Les Touches.

The northern half of the commune is slightly more elevated than the south, with a depression found in the center.

The north part of the commune sits on a formation of schist, sandstone, and volcanic rock (Upper Devonian-Ordovician).

Further south, about 1 kilometre (0.62 mi) wide, there is another formation consisting of schist, psammite, greywacke, and conglomerates (Serpukhovian, early Bashkirian).

Celtic and Gaelic tribes such as the Ligures, the Amoricans, and the Namnetes lived in the area before the arrival of the Romans.

The area around Mouzeil suffered damages due to attacks by Henry Plantagenet in 1175 and King John of England in 1214, and the war of Breton succession from 1341 to 1365.

In 1488, Charles VIII of France and his armies besieged Ancenis and pillaged Mouzeil and the surrounding areas.

Although most of the municipalities in Ancenis did not send any volunteers to enlist in the Garde nationale Mouzeil sent five, the most out of any commune in the district.

The citizens of Mouzeil cheered when he passed by so the Emperor stopped and granted the requests of a widow, who petitioned him for the authorization to open an Inn.
