Toamasina Autonomous Port, Maritime port in Toamasina, Madagascar.

Toamasina Autonomous Port is a maritime facility with multiple berths, container terminals, and warehouse buildings along Madagascar's eastern coast serving as the country's main seaport. The infrastructure includes docks, loading equipment, and storage areas that handle both cargo operations and occasional passenger vessels.

The port is managed by the Société de Gestion du Port Autonome de Toamasina (SPAT), a Malagasy government body, while container operations were contracted to Madagascar International Container Terminal Services, a subsidiary of the Filipino firm International Container Terminal Services Inc. In 2018 SPAT began an expansion financed for two thirds by a 411 million dollar loan from the Japan International Cooperation Agency, repayable over 40 years, intended to quadruple freight capacity and allow larger cargo ships to call.

The port is where local fishing traditions and international maritime activity coexist visibly in daily operations. Workers and traders from different parts of the Indian Ocean region move through the docks, shaping the cultural rhythm of this working waterfront.

The port operates year-round and is managed by multiple operators providing different services to vessels. Access to certain dock areas may be restricted, so it helps to check ahead about conditions before visiting.

The monthly passenger crossing to Réunion and Mauritius uses the MS Mauritius Trochetia, run by Mauritius Shipping Corporation Ltd. The same quays handle about 1,600,000 tonnes of freight a year, three quarters of it in containers, so travellers board beside working cargo berths.
