Antonio Giordani Soika (9 May 1913 – 2 January 1997) was an Italian entomologist, ecologist and director of the Civic Museum of Natural History of Venice (Museo Civico di Storia Naturale). He had a long career in which he worked on various groups of insects but much of his work was on the Hymenoptera. He made great contributions to the knowledge of Neotropical wasps, especially potter wasps for which he produced many taxonomic keys and also monographs on the systematics of the wasp family Vespidae.
