The Botanischer Garten Münster (4.6 hectares) is a botanical garden maintained by the University of Münster (Westfälische Wilhelms-Universität Münster).

It is located directly behind the Prince Bishop's Castle, within the castle grounds at 3 Schloßgarten, Münster, North Rhine-Westphalia, Germany, and open daily free of charge.

The garden was begun in 1803 by Freiherr vom Stein for the university's medical faculty, with first greenhouses built in 1804. From 1806–1815, during the occupation of Westphalia by French troops and the Congress of Vienna, its emphasis changed from medicinal plants to a primary focus on indigenous plants. Its first seed catalog issued in 1827, and its orangery was constructed in 1840. Noted botanist Carl Correns (1864–1933) directed the garden from 1909–1915, with the first tropical greenhouse built in 1935. The garden was severely damaged during World War II, with all its greenhouses destroyed. Even so in 1952 the garden was partially restored and five greenhouses had been rebuilt. An artificial stream, meadow, and moor were created during the 1990s, and in 2005 a new medicinal garden added.

Today the garden contains about 8,000 species, including a major collection of 230 of the 280 known Pelargonium species. In addition to ten greenhouses (total area about 2,000 m²), major garden sections are as follows:
