Sonneratia is a genus of plants in the family Lythraceae. Formerly the Sonneratia were placed in a family called Sonneratiaceae which included both the Sonneratia and the Duabanga, but these two are now placed in their own monotypic subfamilies of the family Lythraceae. The genus was also named Blatti by James Edward Smith, but Sonneratia had botanical nomenclature priority.
