Cullenia is a genus of flowering plants native to India and Sri Lanka. Earlier classification schemes place the genus in the Kapok-tree family (Bombacaceae), but the Angiosperm Phylogeny Group places it in the Malva family (Malvaceae).
The name is after General William Cullen (1785–1862), a Resident in the court of the Maharaja of Travancore who also served as a botanist and meteorologist.
