Gustaf Oskar Andersson Malme (24 October 1864, Stora Malm in Södermanland County – 5 March 1937) was a Swedish botanist.
He studied at Uppsala University, earning his PhD in 1892. From 1905 to 1911 he was a lecturer in biology and chemistry at Högre Latinläroverket in Stockholm. Afterwards, he taught classes in zoology and biology at a teachers' training college in Stockholm.
By way of a travel grant established by Anders Fredrik Regnell, Malme along with botanist Carl Axel Magnus Lindman undertook an expedition to Brazil (Rio Grande do Sul and Mato Grosso) and the central parts of Paraguay in 1892-1894. On the mission the two men collected more than 5000 specimens. In 1901-1903 Malme returned to South America, where he revisited Brazil and also traveled to areas in Paraguay and Argentina (Mendoza Province).
He was the author of over 100 articles in the journal Kungliga Svenska Vetenskapsakademiens Handlingar. The fungi genus Malmeomyces is named after him, as is the plant genus Malmea (family Annonaceae), described by Robert Elias Fries in 1905.
