Hofstenia, or panther worms, is a genus of acoels belonging to the family Hofsteniidae.

They are recognized for their ability to regenerate any missing tissue type and recover body axes following injury including a functional brain during whole-body regeneration. The Hofstenia body is populated by neoblast-like cells, adult stem cells, which are necessary for Hofstenia regeneration, and are frequently studied in planarians.
