Baie-Mahault (French pronunciation: [bɛ ma.o]; Guadeloupean Creole: Bémao) is a commune in the overseas department and region of Guadeloupe, France.

On 29 November 1808, during the Napoleonic Wars, boats from HMS Heureux attacked French vessels in the harbour and the batteries protecting them.

Baie-Mahault (Mangrove Bay) is located in the borough called Canton and it extends a vast plain of northeastern Basse-Terre Island, where it meets Grande-Terre.

A channel, navigable by smaller boats, of from 30 to 100 yards across, called Riviere Salee or Salt River separates the two islands.

It accommodates the Port authority of Guadeloupe, the Complex World Trade Center (logistical center of the CCI of Pointe-à-Pitre), the oil terminals of the SARA (Société Anonyme de la Raffinerie des Antilles), and two power plants.

[7] The industrial and commercial park of Jarry-Moudong is regarded as the economic lung of the Guadeloupe with employment of more than 10,000.

At the end of the borough, below the town hall, a landing at the edge of the lagoon, is the starting point of tours of the bay.

The shopping center of Carrefour, in Destrellan is located in Baie-Mahault, sells French imports, such as cologne, perfumes, clothing, food, etc.

The main sport arena is a single velodrome, the Vélodrome Amédée Détraux, in Gourde-Liane, near Destrellan, and a stadium called Fiesque Duchesne.

Artists that have performed there include Ray Charles, George Benson, Diam's, Al Jarreau, James Brown and Lionel Richie.
