Count: 0 — There are no genuine Norse gods that start with the letter P. Consult the primary Old Norse sources (the Poetic Edda, the Prose Edda, the sagas, and skaldic poems) and standard reference works (for example Rudolf Simek’s Dictionary of Northern Mythology and Andy Orchard’s Dictionary of Norse Myth and Legend) and you will find no deity-name attested with an initial P. Note an interesting detail: Old Norse orthography and sound patterns make initial P uncommon, so the absence is linguistically consistent as well as textually supported.

Understand why this specific search returns nothing. Old Norse uses letters and sounds (þ, ð, and initial f/t/k) that produce the bulk of deity names; P as an initial consonant appears rarely in native names and often signals a later loanword or a modern invention. Manuscript transmission and Latinization also produce spelling variants that can mislead modern readers, so a name that looks like it begins with P in English is often originally written with a different letter or is not a deity at all.

If you expected P-names, look to related categories and near-misses instead. Check Icelandic folklore (for example the folkloric figure Pesta, a personification of plague, which is not an Eddic god) and later literary or modern fictional creations that adopt P-initial names. Consult adjacent letter pages and the index in a reliable A–Z reference to find well-attested gods (Odin, Thor, Freyja) and rarer, reliably sourced names that do appear in the canonical texts.
