America³ (USA–23) (pronounced "America cubed") was an American International America's Cup Class yacht that successfully defended the 1992 America's Cup challenge from the Il Moro Challenge racing syndicate.

America³ was one of four yachts built for the America3 Foundation racing syndicate, headed by American businessman Bill Koch, for the 1992 Citizen Cup.

The America3 Foundation racing syndicate entered the 1995 Citizen Cup with an all women's programme.

The team sailed America³ (USA–23) in the first three stages of the Round Robin, then switched to their newly delivered yacht Mighty Mary (USA–43) for the remainder of the event.

America³ is on display at the Herreshoff Marine Museum in Bristol, Rhode Island.
