Diedrich Henne (1834 – 21 January 1913) was a German-born botanist and plant collector. He emigrated to Australia and was employed as an assistant to the colonial botanist Ferdinand von Mueller at the Melbourne Herbarium. He collected six cases of plants when employed as a botanist on the Burke and Wills rescue expedition. Frederick Manson Bailey lists twelve species of plants in the Queensland herbarium, collected by Henne.
