Azadirachta is a genus of two species of trees in the flowering plant family Meliaceae (Mahogany family). Numerous species have been described in the genus but only two are currently recognized, A. excelsa (Jack) Jacobs, and the economically important Neem tree, A. indica A. Juss. (Mabberley et al. 1995, Pennington & Styles 1975). Both species are native to the Indomalaysian region, and A. indica is also widely cultivated and naturalized outside its native range. The resin from the trees have been attributed with medical benefits.
These species shall not be confused with Melia azedarach L.
