Neonicholsonia is a monotypic genus of flowering plant in the palm family native to Central America (Honduras, Nicaragua, Costa Rica, Panama). The sole species is Neonicholsonia watsonii. The genus and species names honor George Nicholson, a former curator of the Royal Botanic Gardens, Kew and his successor William Watson.
