Gustavia is a genus of flowering plants in the family Lecythidaceae described by Linnaeus in 1775.

[2] Many of the species are threatened; some are critically endangered[5] Gustavia superba, though, is actually abundant in re-growing secondary forests.

It grows in northern South America, from Panama south through the Andes as far as Ecuador, and along the Caribbean coast and in the Amazon basin.

[6] The genus name was given by Linnaeus to honor his king, Gustav III of Sweden.
