In Norse mythology, Hlín (Old Norse "protectress") is a goddess associated with the goddess Frigg. Hlín appears in a poem 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 kennings found in skaldic poetry. Hlín has been theorized as possibly another name for Frigg.
In the Poetic Edda poem Völuspá, Hlín receives a mention regarding the foretold death of the god Odin during the immense battle waged at Ragnarök:
In chapter 35 of the Prose Edda book Gylfaginning, Hlín is cited twelfth among a series of sixteen goddesses. High tells Gangleri (earlier in the book described as King Gylfi in disguise) that Hlín "is given the function of protecting people whom Frigg wishes to save from some danger." High continues that, from this, "someone who escapes finds refuge (hleinar)." In chapter 51, the above-mentioned Völuspá stanza is quoted. In chapter 75 of the book Skáldskaparmál Hlín appears within a list of 27 ásynjur names.
In skaldic poetry, the name Hlín is frequent in kennings for women. Examples include Hlín hringa ("Hlín of rings"), Hlín goðvefjar ("Hlín of velvet") and arm-Hlín ("arm-Hlín"). The name is already used frequently in this way by the 10th-century poet Kormákr Ögmundarson and remains current in skaldic poetry through the following centuries, employed by poets such as Þórðr Kolbeinsson, Gizurr Þorvaldsson and Einarr Gilsson. The name remained frequently used in woman kennings in rímur poetry, sometimes as Lín.
