SEA LIFE Brighton is an aquarium attraction in the English city of Brighton. Opened as Brighton Aquarium in 1872, it is the oldest operating aquarium in the world. The attraction was bought by Sea Life in 1991.

Designed by Eugenius Birch, the site opened as an independent aquarium in 1872 after construction began in 1869. The Aquarium was bombed during the First World War and was reconstructed afterward.

To keep in line with Sea Life's "Breed, Rescue, Protect" message, the aquarium has breeding schemes and "The Big Fish" program which helps educate home aquarium owners on where to buy fish ethically.

Sealife Brighton features over 5,000 sea creatures and over 100 different species. It’s also a Grade II listed heritage building.
