The jardin des plantes d'Angers (4 hectares) is a municipal park and botanical garden located on Place Pierre Mendès France, Angers, Maine-et-Loire, Pays de la Loire, France.
Its first location was on the Château Gontier and Bressigny roads, near today's rue Béclard, but that site proved too small and its rental too uncertain.
The site was cleared in the winter of 1790–1791, and in 1791 Merlet de La Boulaye gave the first free, public course on botany; in the following year, he wrote out a list in alphabetical order of the garden's collections, including the first magnolia in Angers and an agave from America.
The city purchased the grounds of the Saint-Samson church shortly afterwards, and merged them with the botanical garden, with the result declared national property in 1792.
The remaining garden was completely remodeled in 1901–1905 by noted landscape architect Édouard André, famous for his parks in Monte Carlo and Montevideo; today's current garden is in his English style with a cascading stream.
