Henri Gaussen Botanical Garden

The Jardin botanique Henri Gaussen is a botanical garden operated by the Université Paul Sabatier at 39 allées Jules Guesde, Toulouse, Haute-Garonne, Midi-Pyrénées, France. It is open weekdays in the warmer months.

The botanical garden was originally created by Philippe-Isidore Picot de Lapeyrouse in the Jardin des Plantes established within the grounds of a Carmelite monastery requisitioned during the French Revolution. It was divided into sections, and eventually grew to incorporate more than 5000 species from the nearby Pyrenees and around the world.

Today's garden is maintained by the Université Paul Sabatier as an adjunct to the natural history museum of Toulouse.
