Gustav Henrik Andreas Budde-Lund (11 January 1846-19 September 1911) was a Danish invertebrate zoologist. In 1868, he co-founded the Entomologisk Forening, alongside Rasmus William Traugott Schlick, Carl August Møller, Andreas Haas and Ivar Frederik Christian Ammitzbøll. He was a student of entomologist J. C. Schiødte, and became a leading authority on terrestrial isopods (woodlice, pill bugs and relatives), describing over 70 genera and around 500 species.
