埃尔（Eir），她名字的意义是「仁慈」。埃尔是阿萨神族中的一名女神，也是女神弗丽嘉（Frigg）的侍女之一。她负责掌管医疗，号称最好的医生，尤其擅长草药，甚至有使人复活的能力。埃尔据说也是女武神之一。

埃尔除了会治疗身体的伤，她也能治疗心理和感情。她只将这些医疗的技艺传授给女子，所以在古代北欧，医疗是女子的工作。

In Norse mythology, Eir (Old Norse "help, mercy") is a goddess and/or valkyrie associated with medical skill. Eir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; the Prose Edda, written in the 13th century by Snorri Sturluson; and in skaldic poetry, including a runic inscription from Bergen, Norway from around 1300. Scholars have theorized about whether these three sources refer to the same figure, and debate whether Eir may have been originally a healing goddess and/or a valkyrie. In addition, Eir has been theorized as a form of the goddess Frigg and has been compared to the Greek goddess Hygieia.
