Botanischer Garten Augsburg, Municipal botanical garden in Augsburg, Germany.

Botanischer Garten Augsburg is a municipal botanical garden spanning 10 hectares with about 3,100 plant species, including perennials, wild herbs, grasses, and ferns plus a Japanese garden section. The greenhouse complex houses an additional 1,200 tropical and subtropical species.

The garden opened in September 1936 as a teaching and school garden on a 1.7-hectare site next to Siebentischpark, after the city decided in 1935 to relocate its nursery. Air raids in World War II damaged it, and it reopened on 8 July 1950. Preparations for the 1985 Bavarian State Garden Show doubled the area to 10 hectares and added a 4,200 m² Japanese garden.

The Japanese garden covers 4,200 m² and was created for the 1985 Bavarian State Garden Show, supported by Augsburg's partner cities Amagasaki and Nagahama and funded by Stadtsparkasse Augsburg. The entrance area also holds a farmer's garden edged with boxwood, planted with species the Romans knew or spread, recalling Roman Augsburg.

The garden is open daily and features a restaurant, seasonal butterfly exhibitions, and guided tours for visitors. Direct access to the adjacent Augsburg Zoo allows visitors to combine both sites conveniently.

The neorenaissance garden pavilion in front of the administration building was designed by Augsburg architect Karl Albert Gollwitzer in the 19th century. It originally served as a leisure retreat for directors of the Augsburg worsted spinning mill in the garden of their company villa.
