- André Léon Tonnoir (9 April 1885 – 30 January 1940), was a Belgian entomologist. Born in Brussels, Tonnoir studied engineering followed by radiology at university.
- He worked as a technician during World War I, and after the war had ended he worked with the entomology staff at the Royal Belgian Institute of Natural Sciences in Brussels.

- Soon afterwards, he left for Nelson in New Zealand to do research for the Cawthron Institute until 1924.
- In the same year, he moved to Christchurch for two new roles; curator at the Canterbury Museum and lecturer at Canterbury College.
- In 1926, he went back to work for three years at the Cawthron Institute as part of their noxious weeds programme.
- He eventually went back to Australia, working in Canberra as a Senior Ecologist and Curator.
