This article is about the genus of recumbirostran. For the sea serpent in Norse mythology, see Jörmungandr. For the genus of mosasaur, see Jormungandr walhallaensis.

Joermungandr is an extinct genus of recumbirostran tetrapod from the Late Carboniferous Mazon Creek fossil beds of Illinois. It currently contains a single species, Joermungandr bolti. Like many other recumbirostrans, the body is elongated, which is likely an adaptation for fossoriality (digging and living underground).[1]

The genus was named after Jörmungandr, a creature from Norse mythology.[1]
