Ensenada (Spanish pronunciation: [enseˈnaða]) is a city and port in Buenos Aires Province, Argentina, located around the Ensenada de Barragán. It has 31,031 inhabitants as per the 2001 census [INDEC]. It is the capital of Ensenada Partido, and together with Berisso Partido they are the main suburbs of the Gran La Plata conurbation around the provincial capital of La Plata.

The port of Ensenada carries grain and beef exports, as well as industrial shipments. The volume traded has been recently growing at the expense of the Buenos Aires port, located 60 km to the north-west.

As Buenos Aires city authorities are considering repurposing the port of Buenos Aires as a passenger-only facility, the volume at Ensenada (as well as that of the ports in Campana and Bahía Blanca) is slated to experience further growth.
