Thomandersia is the sole genus in the Thomandersiaceae, an African family of flowering plants. Thomandersia is a genus of shrubs and small trees, with six species native to Central and West Africa.cite-ref-w-3-0[3]

Thomandersia traditionally has been classified within the family Acanthaceae based on morphology by several authors, including APG I 1998, APG II 2003, and in Schlegeliaceae at APG Website Missouri Botanical Garden, in a list of genera of this family, but Stevens argues further that should be considered out of this taxon by weak support and regarded Thomandersiaceae.cite-ref-4[4]

The genus was elevated to family status, previously by Sreemadhavan 1976 cite-ref-5[5] and 1977 cite-ref-6[6] on the basis of leaf anatomy and anther morphology, and more recently by Wortley et al. 2005 cite-ref-7[7] and 2007,cite-ref-8[8] based on phylogenetic analyses of genetic material.

The genus was described with this name in 1892 by French botanist Henri Ernest Baillon.cite-ref-9[9]cite-ref-u-1-1[1]
