Urosalpinx cinerea, common name the eastern oyster drill, Atlantic oyster drill, or just oyster drill, is a species of small predatory sea snail, a marine gastropod mollusk in the family Muricidae, the murexes or rock snails.

This snail uses chemoreception to locate its invertebrate prey, which is typically a sessile or encrusting organism that is unable to escape its pursuer. The chemoreception hunting strategy involves detecting microscopic particles that its prey releases into the sea water.

The Atlantic oyster drill is a serious problem in commercial oyster beds, and it has been accidentally introduced well outside its natural range.
