Mar del Plata Aquarium, Marine park in Mar del Plata, Argentina.

The Mar del Plata Aquarium stands beside the Punta Mogotes lighthouse on the Atlantic coast. Its habitats hold one- and two-haired sea lions, Magellanic, rockhopper and king penguins, dolphins, lemurs, fish and native and exotic birds, alongside a tortoise enclosure, a Pampean lagoon and a sea theatre. Architects Haydeé Pérez Maraviglia and Carlos Mariani designed the complex, which opened on 9 July 1993.

The facility opened in 1993 and was designed by architect María Haydee Pérez Maraviglia. New management took over in 2018 and focused on marine animal care.

The name reflects its location on the coast and focus on sea life. Visitors observe daily feeding sessions and care routines that show how staff interact with marine animals and support their wellbeing.

Visitors find several attractions like dolphin shows, sea lion performances, and a 3D theater spread throughout the day. Direct access to Aquarium Beach is available from the facility.

The facility includes a rehabilitation center for injured marine animals found along the Argentine coast. Visitors can observe how animals receive medical care and preparation for return to the sea.
