Ratatoskr, in Norse mythology, is a squirrel that runs up and down the world tree Yggdrasil, carrying messages between the eagle perched atop the tree and the serpent Níðhöggr, who dwells beneath one of the three roots of the tree. This cosmic squirrel is mentioned in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and in the Prose Edda, written in the 13th century by Snorri Sturluson.

The name Ratatoskr is commonly interpreted to mean "drill-tooth" or "bore-tooth", which may refer to the squirrel's habit of gnawing on the branches of Yggdrasil. Some scholars suggest that Ratatoskr's role in carrying messages between the eagle and the serpent represents the spread of gossip or malicious words, as the two creatures are often depicted as being in constant conflict. This interpretation paints Ratatoskr as a mischievous character who may enjoy stirring up trouble between the different realms connected by Yggdrasil.

While Ratatoskr plays a relatively minor role in the surviving Norse myths, his presence highlights the interconnectedness of the Norse cosmos and the constant communication between different realms and beings. The image of a squirrel racing up and down the world tree also serves as a vivid representation of the dynamic and ever-changing nature of the Norse mythological universe, where even seemingly insignificant creatures can play important roles in maintaining the cosmic balance.
