Hávamál is presented as a single poem in the Codex Regius, a collection of Old Norse poems from the Viking age. A scholarly estimate of Hávamál's age dates the poem to between 900 and 1000 A.D. The poem, itself a combination of numerous shorter poems, is largely gnomic, presenting advice for living, proper conduct and wisdom. It is considered an important source of Old Norse philosophy.

Codex Regius or GKS 2365 4º is an Icelandic codex in which many Old Norse poems from the Poetic Edda are preserved. Thought to have been written during the 1270s, it is made up of 45 vellum leaves. The work originally contained a further eight leaves, which are now missing. It is the sole source for most of the poems it contains. In scholarly texts, this manuscript is commonly abbreviated as [R] for Codex Regius, or as [K] for Konungsbók.
