Félix Delahaye (born 1767 and died 1829) was a French gardener who served on the Bruni d'Entrecasteaux voyage (1791–93) that was sent by the French National Assembly to search for the missing explorer Jean-François La Perouse. He was also one of the earliest European gardeners to work in Australia. On returning to France Delahaye eventually became Head Gardener to Empress Josephine at the Château de Malmaison.
