Blapsium is an extinct genus of beetles from the Middle Jurassic of England. The only described species is B. egertoni, which is known from a single specimen found by the Earl of Enniskillen at the Taynton Limestone Formation, also known as the Stonesfield Slate. The specimen is deposited in the Natural History Museum, London. It is incompletely preserved, lacking a head, pronotum and legs. It has a broad, convex body. It has a very short metathorax, which suggests that it was possibly apterous.

In his original description of the genus, John O. Westwood compared Blapsium to the darkling beetles and ground beetles. Ponomarenko (2006) redescribed the holotype of B. egertoni and referred it to the tribe Notocupedini in the family Ommatidae (considered in the paper to be a subfamily of Cupedidae), which was followed by Kirejtshuk (2020).
