Botanischer Garten der Stadt Wilhelmshaven, Botanical garden in Wilhelmshaven, Germany.

The Botanischer Garten der Stadt Wilhelmshaven covers 6000 square metres at Neuengrodener Weg 26, next to the Rosarium and the Stadtpark. It is Germany's smallest botanical garden. Its outdoor beds group plants of northwestern Germany by habitat, and greenhouses hold Mediterranean, tropical and subtropical species.

The garden began in 1947 as a school project on the grounds of Grodenschule, which had been damaged during World War II bombing raids. It was later developed into a public botanical garden to serve the community's interests.

The garden displays plants from Mediterranean, tropical, and subtropical regions that visitors can explore throughout the year. These collections help people understand how different climates support very different types of plant life and crops.

The garden is easy to walk through, with clearly marked plant zones and areas that help visitors navigate the space. Signage throughout explains the different plant groups and natural environments on display.

The garden is Germany's smallest botanical garden, covering 6,000 square metres at its Neuengrodener Weg site since reopening on 9 June 2017. Its earlier Gökerstraße site, founded in 1947 on the grounds of the bombed Grodenschule, measured 8,500 square metres and held around 2,500 mostly native plant species.
