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

[1] The genus Alberta was shown to be paraphyletic in a phylogenetic analysis of the tribe Alberteae.

The type species Alberta magna is set apart from the Malagasy Alberta species.

A new genus, Razafimandimbisonia, was proposed to accommodate these Malagasy species.

It is named in honour of the botanist Sylvain G.
