Louis Lavauden (19 June 1881, in Grenoble – 1 September 1935, in Anjou, Isère) was a French zoologist and forester. He was a student at the Institut agronomique et de l'Ecole forestière in Nancy, afterwards conducting zoological studies of the province Dauphiné. In 1912–13 he performed research of the fauna in Algeria and Tunisia, and following World War I, returned to Tunisia as a forester. In 1925 he took part in one of the first motorized crossings of the Sahara (from Tunis to Cotonou via Lake Chad). From 1928 he was stationed in Madagascar, where he collected zoological specimens that included a number of lemur species.
