Claude-Francois Joseph Louis Receveur O.F.M. Conv., (1757 – 17 February 1788) was a French friar priest, naturalist and astronomer who sailed with Jean-François de Galaup, comte de La Pérouse. Receveur was also considered a skilled botanist, geologist, chemist, meteorologist, and philologist and has been described as being as close as one could get to being an ecologist in the 18th century.
