Justin Girod-Chantrans (26 September 1750, Besançon – 1 April 1841, Besançon) was a French naturalist known for his pioneer research in the field of phycology.

Following studies with the Jesuits, he entered the Ecole du Génie militaire in 1768. Several years later, he attained the title of captain (1777), subsequently serving at different military posts (including Saint-Domingue) until 1791. Around 1786, he developed an interest in natural history.

In 1799 he founded the Société d'agriculture, commerce et arts in Besançon. He then became involved in politics, being elected to the legislature in 1802. Beginning in 1810, he devoted all his time and energy to natural sciences.

He described a number of phycological species; Haematococcus lacustris, Volvox lacustris and Conferva mammiformis being a few examples.[1]
