Carlos de Amésquita (also Carlos de Amézqueta or Carlos de Amézola) was a Spanish naval officer of the 16th century. He is remembered for an action taken while on a naval patrol, known as the Battle of Cornwall, during the Anglo-Spanish War 1585–1604. Amésquita commanded three companies and four galleys (named Capitana, Patrona, Peregrina and Bazana). They disembarked at Penmarch on July 26, and in the Mount's Bay (Cornwall) on August 2.
