In Norse mythology, Níðhöggr ( Malice Striker, often anglicized Nidhogg ) is a dragon who gnaws at a root of the World Tree, Yggdrasill.

According to the Gylfaginning part of Snorri Sturluson's Prose Edda, Níðhöggr is a being which gnaws one of the three roots of Yggdrasill.

This root is placed over Niflheimr and Níðhöggr gnaws it from beneath.

In Norse mythology, Ratatoskr ( Old Norse, generally considered to mean " drill-tooth " or " bore-tooth ") is a squirrel who runs up and down the world tree Yggdrasil to carry messages between the unnamed eagle, perched atop Yggdrasil, and the wyrm Níðhöggr, who dwells beneath one of the three roots of the tree.

In particular, he carried messages between the unnamed eagle at the top of Yggdrasill and the wyrm Níðhöggr beneath its roots.

In this context, the animal may be interpreted as Níðhöggr eating the roots of Yggdrasil.

Creatures live within Yggdrasil, including the wyrm ( dragon ) Níðhöggr, an unnamed eagle, and the stags Dáinn, Dvalinn, Duneyrr and Duraþrór.

Snorri's knowledge of Níðhöggr seems to come from two of the Eddic poems: Grímnismál and Völuspá.

The poem identifies Níðhöggr as tearing at the tree from beneath and also mentions Ratatoskr as carrying messages between Níðhöggr and the eagle who lives at the top of the tree.

The root over Niflheim is gnawed at by the wyrm Níðhöggr, and beneath this root is the spring Hvergelmir.

In Norse mythology, Náströnd ( Corpse Shore ) is a place in Hel where Níðhöggr lives and sucks corpses.

Later in Skáldskaparmál, Snorri includes Níðhöggr in a list of various terms and names for swords.

The poem Völuspá mentions Níðhöggr twice.

* In the Völuspá the being Níðhöggr is identified as a dragon ( Old Norse: dreki )
