Charles-Pierre Boullanger (1772-1813) was a French geographer who served on Nicolas Baudin’s scientific expedition to the South Seas from 1800 to 1803. He was a midshipman cartographer and hydrographic engineer on the survey vessel Le Géographe with the sister ship Naturaliste. During this expedition he produced, with Charles-Alexandre Lesueur, a detailed map of the east coast of Australia.
Boullanger led a small group sent by Nicolas Baudin to Maria Island off the east Tasmanian coast on 19 February 1802.
