Domenico Agostino Vandelli (Padua, 8 July 1735 – Lisbon, 27 June 1816) was an Italian naturalist, who did most of his scientific work in Portugal.
He studied at the University of Padua, from which he received a doctorate in Natural Philosophy and Medicine in 1756. While active as naturalist in Italy he began a correspondence with the Swedish naturalist Carl von Linné, which continued for several years. In 1763 he was invited by Catherine the Great of Russia to join the faculty of the University of St. Petersburg, but he declined.
His contributions to zoology have been recognized by another species of Blanus named after him, Blanus vandellii,[4] (although he is cited in the description as Domingos Vandelli).
