Alessandro Malaspina (November 5, 1754 – April 9, 1810) was an Italian explorer who spent most of his life as a Spanish naval officer. Under a Spanish royal commission, he undertook a voyage around the world from 1786 to 1788, then, from 1789 to 1794, a scientific expedition (the Malaspina Expedition) throughout the Pacific Ocean, exploring and mapping much of the west coast of the Americas from Cape Horn to the Gulf of Alaska, crossing to Guam and the Philippines, and stopping in New Zealand, Australia, and Tonga.
