Plumeria (), also known as frangipani, is a genus of flowering plants in the subfamily Rauvolfioideae, of the family Apocynaceae. Most species are deciduous shrubs or small trees. The species are native to the Neotropical realm (in Mexico, Central America, and the Caribbean, and as far south as Brazil and as far north as Florida in the United States), but are often grown as cosmopolitan ornamentals in tropical regions, especially in Hawaii, as well as hot desert climates in the Arabian Peninsula with proper irrigation.
