Ilmr is a figure in Norse mythology who is listed as a goddess and who occurs in skaldic kennings. Her associations and original nature are unknown. Ilmr is attested at two points in the so-called Nafnaþulur appended to the Prose Edda book Skáldskaparmál: between Iðunn and Bil in a list of ásynjur, and in a list of words that can be used in kennings for "woman". No further information other than her name is provided. She is not mentioned in Eddic poetry, but her name does occur several times in skaldic poetry of the 10th and 11th centuries, particularly in verses by Kormákr Ǫgmundarson.
