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.
