The Jardin botanique exotique de Menton (French pronunciation: [ʒaʁdɛ̃ bɔtanik ɛɡzɔtik də mɑ̃tɔ̃]; 11,000 m2), also known as the Jardin botanique exotique du Val Rahmeh, is a botanical garden located off Avenue St Jacques, Menton, Alpes-Maritimes, Provence-Alpes-Côte d'Azur, France.

In 1905 Lord Percy Radcliffe, former governor of Malta, with his spouse Rahmeh acquired the property, adding adjacent farmland to form a garden.

Today the garden contains some 1,500 taxa growing within a microclimate of high humidity where temperatures rarely fall below 5 °C (41 °F) in winter.

Rare species include Aloe marlothii, Araucaria columnaris, Castanospermum australe (Moreton Bay chestnut), Cnicothamnus lorentzi, and Ficus religiosa.

A small rainforest area contains bamboo, gingers, philodendrons, tropical fruit trees, and a path through spices and herbs.
