How Many Norse Realms Are There?
Nine — the Nine Worlds, joined by the world-tree Yggdrasil. But here is the catch almost no one mentions: no surviving Norse text actually lists them. The number is stated; the roster of nine is a modern reconstruction, and two of its slots are genuinely contested.
The Yggdrasil Map
Tap any realm to meet its people. Then spotlight the two that make "nine" a reconstruction.
Spotlight the contested realms and the problem is plain: only seven are unambiguously their own world. The "nine" needs you to split the dwarf-realm in two, or to count Hel apart from Niflheim.

The number is real. The list is reconstructed.
The number nine saturates Norse myth. Odin hangs on Yggdrasil for nine nights to win the runes; the god Hermóð rides nine nights down to Hel; the giant Ægir has nine daughters. And in the Völuspá, the opening poem of the Poetic Edda, the seeress declares that she remembers "níu heima" — nine worlds. So the number is unquestionably part of the tradition.
What no source does is list them. The Völuspá names nine worlds and then moves on. Snorri Sturluson's Prose Edda (c. 1220) describes Yggdrasil as having three roots reaching three places — to the Æsir, to the frost-giants, and to Niflheim — not a tidy diagram of nine realms. The familiar map you see everywhere is assembled by modern scholars from scattered names across many poems. It is a very good reconstruction. It is still a reconstruction.
The two slots that wobble
Snorri names Svartalfheim, home of the "dark elves." The Völuspá names Nidavellir, where the dwarves have a hall. Are these two worlds, or two names for one? If they're one, you're a realm short of nine — which is why some lists split them and others don't.
Helheim, the realm of the dead, is sometimes treated as its own world and sometimes placed inside Niflheim, the primordial mist. Count them as two and you reach nine comfortably; count them as one and you're short again.
Resolve both the "modern" way and you get a clean nine. Resolve them strictly and you get seven solid worlds plus two judgement calls. The number survived; the bookkeeping never did.
Life on the tree
Yggdrasil isn't a quiet diagram — it's a noisy, gnawed, suffering tree, full of creatures with very specific jobs.
These details come mostly from a single source-poem, Grímnismál, and from Snorri's retelling of it — which is part of why the cosmology feels so vivid in places and so blank in others.

Frequently asked
Is it definitely nine realms?
Nine is the number the sources give, and it is the standard answer. But because no text lists nine worlds by name, the specific roster is reconstructed — and the dwarf-realm and the status of Hel mean you can argue the firmly-attested total down to seven.
Are Asgard and Valhalla different things?
Yes. Asgard is the whole realm of the Æsir gods. Valhalla is one hall within it — Odin’s hall, where half of those slain in battle feast until Ragnarök.
Why does the number nine appear so often?
Nine was a deeply significant number in Norse and wider Germanic culture, recurring in rituals and myths — nine nights, nine daughters, nine worlds. The cosmology’s "nine" sits inside that pattern.
Where did the popular nine-realms diagram come from?
From modern scholars and, increasingly, popular culture and games assembling the scattered Eddic names into a single tidy chart. It is a useful map, but it is a reconstruction rather than a medieval original.

The Norse were certain there were nine worlds. They just never got around to agreeing which nine — and the gap is where the magic lives.
