Jean Nicolas Collignon (1762–?1788) was a gardener and botanist from the Jardin du Roi who served on the La Pérouse expedition to the South Seas (1785–?1788). Following the three voyages of James Cook, French King Louis XVI had commanded a similar expedition be sent out by France. The La Pérouse expedition consisted of the frigates La Boussole, the flagship with Collignon in the crew, and L’Astrolabe under the command of Fleuriot de Langle. The two ships left Brest on the 1 August 1785 and were last seen at Botany Bay, New Holland on 26 January 1788.
