Lithophaga, the date mussels, are a genus of medium-sized marine bivalve molluscs in the family Mytilidae. Some of the earliest fossil Lithophaga shells have been found in Mesozoic rocks from the Alps and from Vancouver Island.[2][3]

The shells of species in this genus are long and narrow with parallel sides. The animals bore into stone or coral rock with the help of pallial gland secretions,[4] hence the systematic name Lithophaga, which means "stone-eater". Their club-shaped borings are given the trace fossil name Gastrochaenolites.[3]
