Polyscias is a genus of flowering plants in the family Araliaceae. They bear pinnately compound leaves.

In 2003, a Checklist and nomenclator was published for Araliaceae. In this work, 116 species were listed for Polyscias. The species list in this article consists of those species plus the unpublished species Polyscias nothisii Lowry. The latter is one of about 10 species from New Caledonia that will be described in a forthcoming paper.
