Aquarius is an underwater habitat located in the Florida Keys National Marine Sanctuary. It is the only underwater research facility in the world dedicated to science. Aquarius is owned by the National Oceanic and Atmospheric Administration (NOAA) and operated by the National Undersea Research Center (NURC) at the University of North Carolina–Wilmington.

Aquarius was built in Victoria, Texas, in 1986. Underwater operations first began in the U.S. Virgin Islands. Following Hurricane Hugo in 1988 Aquarius was taken to NURC for repairs and refurbishment and was redeployed in the Florida Keys in 1992. Aquarius is located under 20 m (64 ft) of water at the base of a coral reef within the Florida Keys National Marine Sanctuary, an ideal site for studying the health of sensitive coral reefs.

The habitat accommodates four scientists and two technicians for missions averaging ten days. Scientists on the Aquarius are often called "aquanauts". Dives from Aquarius can last for up to nine hours at a time, by comparison surface dives usually last between one to two hours. Long dive times allow for observation that would not otherwise be possible.

Returning to the water surface takes 17 hours so that workers do not suffer decompression sickness. Several missions on the Aquarius have been cancelled due to hurricane activity.
