Jules Poret de Blosseville (29 July 1802 – August 1833) was a French naval officer, geographer and explorer. Born in 1802, he joined the French Navy at the age of 16. From 1822 to 1825, he participated in an expedition that explored the South Pacific and, by its conclusion, circumnavigated the world. He disappeared in August 1833, while in command of his own expedition to the Arctic.
