Nauclea is a genus of flowering plants in the family Rubiaceae.

[3] It refers to the resemblance of the cells of the capsule to a ship's hull.

[4] Nauclea diderrichii is a large tree from West Africa that is widely cultivated elsewhere.

It is closely related to Burttdavya and Sarcocephalus,[6] and these latter two genera are now considered synonyms of Nauclea.

[7] The current type species for the genus is Nauclea orientalis.
