Cancun Underwater Museum is a series of sculptures by Jason deCaires Taylor placed underwater off the coast of Isla de Mujeres and Cancún, Mexico. The project began in November 2009 with placement of a hundred statues in shallow waters of the Cancún National Marine Park, which had been previously damaged by storms. The sculptures are created with pH-neutral marine concrete and are based on members of the local community. The artist planned the sculptures as artificial reefs with fire coral planted in the initial sculptures. A total of 400 sculptures were installed by the end of 2010.
Snorkeleres, scuba divers, and tourists in glass-bottom boats all visit the underwater installation.
