Grippia is a genus of early ichthyopterygian, an extinct group of reptiles that resembled dolphins. Its only species is Grippia longirostris. It was a relatively small ichthyopterygian, measuring around long. Fossil remains from Svalbard from the specimen SVT 203 were originally assigned to G. longirostris but are now thought to have belonged to a non-ichthyopterygian diapsid related to Helveticosaurus.

==Discovery== Fossils have been found along the coasts of Greenland, China, Japan, Norway, and Canada (Sulfur Mountain Formation); of Early Triassic age. No complete skeletons have ever been found. However, well-preserved remains have been found, with the most notable ones including: The Marine Ironstone found in Agardh Bay Norway. This specimen consists of a partial skull fossil; however, it was lost during World War II and presumably destroyed. Previously, the Vega Phroso Siltstone Member of the Sulphur Mountain Formation in British Columbia. This specimen consists of a well preserved forelimb, several ribs, and a single centrum. However, it has now been reclassified as Gulosaurus helmi, a close relative of Grippia.
