Jules Poret de Blosseville (29 July 1802 – August 1833) was a French naval officer, geographer and explorer.

[1] In August 1822, Blossville was selected as a midshipman on Louis Duperrey's expedition aboard La Coquille[Note 1] to explore the South Pacific.

[3] With Lieutenant Jules Dumont d'Urville,[3] well known for his role in the discovery of the Venus de Milo statue,[5] as second in command, it was intended to sail to several islands in the region, conducting hydrographical and ethnological surveys.

Blosseville's berth on La Coquille was due to the influence of his father, who was acquainted with the Minister of the Navy, Duc de Clermont-Tonnerre.

After stopping at Brazil and the Falkland Islands,[6] the French rounded Cape Horn on 31 December 1822 and travelled along the coast to Peru, conducting hydrographic surveys.

[7] While at Sydney in Australia, Blosseville was invited by Sir Thomas Brisbane, the governor of New South Wales to work in his newly built observatory.

[11] They sailed onto New Zealand, arriving in the Bay of Islands in April 1824,[12] where Blosseville undertook surveying work and explored the area inland.

[17] Instead, Blosseville worked on a number of publications; he was a contributor to an atlas of landscapes and portraits,[16] and wrote a report on New Zealand which was published in 1826, first as part of a periodical and then as a separate document.
