Lagoon catamaran is a brand of twin-hulled boats that are designed and produced in Bordeaux, France.

The company began in 1984 as a specialist multihull division of Jeanneau, a volume monohull constructor.

Jeanneau sold the division to Construction Navale Bordeaux (CNB), which was purchased by Beneteau in 1995, another French boat manufacturer.

Lagoon boats smaller than 50 ft (15 m) are built at Belleville-sur-Vie and launched at Les Sables-d'Olonne in Vendée.

[19] Lagoon boats are made of balsa wood core sandwiched between fiberglass layers which are vacuum infusion molded.
