Otto Huber (born 1944 in Bischofswiesen, Bavaria, Germany) is an Italian ecologist known for his work on the botany, phytogeography and conservation of the neotropics. His academic focus has primarily been on the non-forested biomes of the Venezuelan Guayana. Beginning in the 1970s, he led many pioneering expeditions to the inaccessible tepuis (table mountains) of the region. Huber has authored over 120 publications, including most of the first volume of Flora of the Venezuelan Guayana. As a plant collector, Huber was most active around the period 1974-1999. His herbarium collections number more than 13,500 specimens, each with three to four duplicates on average. Huber worked closely with Julian A. Steyermark, one of his early mentors.
