Jean Marie Bosser (23 December 1922 – 6 December 2013), sometimes listed as Jean-Michel Bosser was a French botanist and agricultural engineer who worked extensively in Madagascar and Mauritius.
Bosser was a researcher at the Laboratoire de Phanérogamie at the Muséum national d'histoire naturelle in Paris. From 1962 to 1963 he was the director of ORSTOM (Office de la recherche scientifique et technique outre-mer, now Institut de recherche pour le développement) in Antananarivo, Madagascar. Together with Thérésien Cadet and Joseph Guého he contributed to the series Flore des Mascareignes published by the Institut de recherche pour le développement (IRD), the Mauritius Sugar Industry Research Institute (MSIRI), and the Royal Botanic Gardens, Kew since 1976 and is a comprehensive work on the flora of Mauritius, Réunion, and Rodrigues. Bosser described numerous new species from Madagascar and the Mascarenes, such as Bulbophyllum labatii, Cynanchum staubii and Cynanchum guehoi. As of June 2014 the International Plant Names Index (IPNI) lists 318 taxa (including many orchids) described by Bosser either as sole author or as a co-author.
