Grímnismál is one of the mythological poems of the Poetic Edda. It is preserved in the Codex Regius manuscript and the AM 748 I 4to fragment. It is spoken through the voice of Grímnir, one of the many guises of the god Odin. The very name suggests guise, or mask or hood. Through an error, King Geirröth tortured Odin-as-Grímnir, a fatal mistake, since Odin caused him to fall upon his own sword. The poem is written mostly in the ljóðaháttr metre, typical for wisdom verse.

The Poetic Edda is the modern name for an untitled collection of Old Norse anonymous narrative poems in alliterative verse. It is distinct from the closely related Prose Edda, although both works are seminal to the study of Old Norse poetry. Several versions of the Poetic Edda exist: especially notable is the medieval Icelandic manuscript Codex Regius, which contains 31 poems.
