恐蝦綱（學名：Dinocaridida）是节肢動物門之下一個已绝灭的海洋生物化石的分類單元。這個綱的學名源於古希臘文，意思就是「恐怖」+「蝦」/「蟹」。除了Schinderhannes bartelsi只見於寒武纪，其餘物種皆為奥陶纪時期的物種^[3]。 It is subdivided into the anomalocaridids and the opabinids. The name of this group comes from Greek, "deinos" and "caris", meaning "terror shrimp" or "terror crab", due to their crustacean-like appearance and the hypotheses suggesting that members of this class were amongst the dominating and most diverse 顶级掠食者 of their time.^[4]

Dinocaridids are Bilateral symmetry（英语：Bilateral symmetry）, with a non-mineralized cuticle（英语：cuticle） and a body divided into two major Tagma (biology)（英语：Tagma (biology)）, or body-sections. The frontal section have two claws found just in front of the mouth, which is located on these creatures' underside. The body will possess thirteen or more segments, each with its own gill branch and swimming lobe. It is thought that these lobes moved in an up-and-down motion to propel the animal forward ^[5] in a fashion similar to the 墨鱼目.

The placement of Dinocaridida is uncertain: they appear to be a stem group（英语：stem group） to arthropods. In some recent works they are grouped with other enigmatic forms in the phylum 葉足動物.^[6]

The group is geographically widespread, and has been reported from Cambrian strata in Canada, China and Russia,^[7] as well as the Ordovician of Morocco and Devonian of Germany.^[8]
