Eir is the Norse goddess associated with healing and medical skill. Her reputation rests on a small number of important references rather than a large cycle of surviving myths.
In the Prose Edda’s Gylfaginning, Eir is listed among the ásynjur, or goddesses, and described as an exceptionally good physician. The Poetic Edda poem Fjölsvinnsmál places Eir among the maidens attending Menglöð on Lyfjaberg, a name commonly interpreted as “healing hill.” The poem suggests that these figures can aid people who make offerings to them.
Eir’s name is often connected with protection, help, or mercy. She also appears in a list of valkyrie names in another section of the Prose Edda, and that has led scholars to debate whether the sources describe one figure or more than one. Some researchers therefore call her a goddess, a valkyrie, or a healing spirit.
That scholarly uncertainty does not change the standard quiz answer. Eir is the figure most directly associated with healing. Freyja and Frigg are major goddesses, but medicine is not their defining traditional role.
