Gustav Henrik Andreas Budde-Lund (11 January 1846 – 19 September 1911)[1] 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.

[citation needed] 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.

[2] He married in 1875 and in 1885 produced his seminal work Crustacea Isopoda terrestria.

[3] The woodlouse genus Buddelundiella was named in Budde-Lund's honour by Filippo Silvestri in 1897.
