Aquarium of the Americas, Public aquarium in French Quarter, New Orleans, USA.

The Audubon Aquarium of the Americas occupies a riverfront complex whose beige facade carries a blue shark graphic and the words "Audubon Aquarium of the Americas", with "ENTERGY IMAX THEATRE" mounted beside it. A tall cylinder of greenish rectangular glass panes rises above the beige section; inside, this glass cylinder encloses the humid Amazon exhibit. The building holds 10,000 animals of 530 species, including a 30-foot tunnel through a 132,000-gallon Caribbean reef tank and a 400,000-gallon, 17-foot-tall Gulf of Mexico tank.

The aquarium opened on September 1, 1990, run by the Audubon Nature Institute, which also oversees the Audubon Zoo and Audubon Park. Hurricane Katrina struck in 2005; the building stayed dry on high ground, but failed backup generators killed most of the 10,000 fish. Nineteen penguins survived and were sent to other facilities. The aquarium reopened on May 26, 2006, after donations and a sponsorship program, and a $41 million renovation brought the Insectarium into the building on June 8, 2023.

The aquarium's name honours John James Audubon, the ornithologist and painter who worked in New Orleans in the 1820s. Its exhibits are grouped by region of the Americas, from the Amazon greenhouse cylinder to the Mississippi River gallery with its leucistic white alligator. The Gulf of Mexico tank was rebuilt after 2005 to show sharks and sea turtles around an oil-rig platform.

The facility sits along Canal Street near the French Quarter and welcomes visitors throughout the day. Consider purchasing a combined ticket that includes access to the adjacent Insectarium, allowing you to experience both buildings in a single visit.

The glass cylinder housing the Amazon exhibit is a landmark on the riverfront; inside, a climate-controlled greenhouse holds macaws, piranhas, an anaconda and freshwater stingrays. After Hurricane Katrina, 19 penguins survived and were moved to other facilities before returning once the aquarium reopened on May 26, 2006.
