Adina is a genus of 12 species[1] of flowering plants in the family Rubiaceae.

The terminal vegetative buds are inconspicuous and loosely surrounded by the stipules.

[3] Adina was named by Richard Salisbury in 1807 in his book, The Paradisus Londinensis.

[4] The genus name is derived from the Ancient Greek word adinos, meaning "clustered, crowded".

[3] Molecular phylogenetic studies have shown that Adina is paraphyletic over Adinauclea, a monospecific genus from Sulawesi and the Moluccas.
