Poranthereae is a tribe in the flowering plant family Phyllanthaceae. It is one of ten tribes in the family, and one of four tribes in the subfamily Phyllanthoideae. Poranthereae comprises about 111 species, distributed into eight genera. The largest genera and the number of species in each are Actephila (31), Meineckia (30), and Andrachne (22).
The tribe consists of herbs, shrubs, and small to medium trees. They have a cosmopolitan distribution, occurring on all continents, except Antarctica. The circumscription and classification of Poranthereae were substantially revised following phylogenetic analysis of DNA sequences from members of the family Phyllanthaceae.
Within Poranthereae, groups of related genera are strongly correlated with habitat and geographical distribution. For example, Notoleptopus, Pseudophyllanthus, and Poranthera are restricted to the Old World Southern Hemisphere.
