Elatostema is a of flowering plants containing approximately 350 known in the nettle Urticaceae, native to tropical forest clearings throughout Australasia, Asia and Africa.

There may be as many as 1,000 of this little-known , which is susceptible to deforestation and other forms of exploitation.

Some , for instance the recently discovered E. fengshanense, show unusual adaptations to growing in deep shade in caves.

DNA analysis suggests that the three genera Elastostema, Pellionia, and Pilea be grouped together as one.
