The Neuer Botanischer Garten der Universität Göttingen (36 hectares), also known as the Experimenteller Botanischer Garten, is a research botanical garden maintained by the University of Göttingen. It is located immediately adjacent to the university's Forstbotanischer Garten und Arboretum at Grisebachstraße 1, Göttingen, Lower Saxony, Germany, and open daily without charge.
The garden was established by Prof. Heinz Ellenberg (1913–1997) in 1967 as an experimental facility to augment the historic Alte Botanische Garten der Universität Göttingen. In 2009 its name was changed to the Experimenteller Botanischer Garten.
The garden contains special collections of Centaurea and related genera, native flora of Central Europe, holarctic forest vegetation, endangered wild plants, and rare weeds, as well as an alpine garden (5000 m²), wild rose collection, and pond (400 m²) with aquatic and swamp plants.
