The Conservatoire botanique national méditerranéen de Porquerolles (180 hectares) is a national conservatory and botanical garden located within the Parc National de Port-Cros on Porquerolles in the Îles d'Hyères, Var, Provence-Alpes-Côte d'Azur, France.
Active conservation on Porquerolles began in 1971 when the state bought 80% of the island to protect it from development.
The conservatory itself was founded in 1979 and became a Conservatoire botanique national in 1990 to serve the French Mediterranean regions of Languedoc-Roussillon, Provence, and the Côte d'Azur.
It also conserves some 2,000 plant genes in its seed bank.
