Louis-Isidore Duperrey (21 October 1786 – 25 August 1865) was a French naval officer and explorer.

On the return to France in March 1825, Lesson and Dumont brought back to France an imposing collection of animals and plants collected on the Falkland Islands, on the coasts of Chile and Peru, in the archipelagos of the Pacific and New Zealand, New Guinea and Australia.

During the voyage the ship spend two weeks in the Bay of Islands in the north of New Zealand in 1824 and visited for ten days on l'île d'Oualan,[1] now Kosrae, contemporary Federated States of Micronesia, that same year.

[3] He was the first to put together on a map the whole Gilbert Islands archipelago, which are now part of Kiribati (with the name given to it by Admiral Krusenstern).

The Australian eastern three-lined skink, Bassiana duperreyi (Gray, 1838), was named in his honour.
