Albert Jean Baptiste Marie Vayssière (8 July 1854, Avignon – 13 January 1942, Marseille) was a French scientist, a biologist, specifically a malacologist and entomologist, i.e. someone who studies mollusks, and insects. Within the Mollusca, Vayssière specialized in sea slugs and bubble snails, i.e. marine opisthobranch gastropods. He made significant contributions towards a better understanding of the general biology, phylogenetic relationships, biogeography and ecological distribution of the group.
From 1873 to 1883, Vayssière served as a préparateur to the Faculté des Sciences at Marseille, where afterwards he was maître de conférences (lecturer). He later served as a professor of zoology, and in 1915 he was appointed director of the Muséum d'histoire naturelle de Marseille.
Vayssière was also interested in entomology, in particular, the field of agricultural entomology.
