The Newport Tower (also known as: Round Tower, Touro Tower, Newport Stone Tower and Old Stone Mill) is a round stone tower located in Touro Park in Newport, Rhode Island (USA), the remains of a windmill built in the mid-17th century.

The tower has received attention due to speculation that it is actually several centuries older and would thus represent evidence of pre-Columbian trans-oceanic contact. Carbon dating shows this belief to be incorrect.
