An aasimar is a creature in the Dungeons & Dragons fantasy role-playing game. Aasimar are "planetouched"; that is, they are mortal creatures that have in their blood some otherworldly characteristics. Aasimar are descended from devas, angels and other creatures of pure good alignment; although their celestial ancestor may be many generations removed, their presence still lingers. Aasimar are predisposed to Good alignments, but they are by no means always good.

The evil-alignment-derived counterparts to aasimar are called tieflings.
