Louis Hildebrand Mandelli (1833–1880) was an Italian settler in India, a tea planter and amateur zoologist and ornithologist. Living in Darjeeling and collecting specimens of birds and animals around Sikkim, he discovered many species from the region and several were named after him. He is honoured in the names Locustella mandelli, Mandelli's Snowfinch and Mandelli's mouse-eared bat.
