The Satohama Shell Midden (里浜貝塚) is an archaeological site consisting of a shell midden and the remains of an adjacent Jōmon period settlement located in what is now the city of Higashimatsushima, Miyagi Prefecture in the Tōhoku region of northern Japan.

The middens associated with such settlements contain bone, botanical material, mollusc shells, sherds, lithics, and other artifacts and ecofacts associated with the now-vanished inhabitants, and these features, provide a useful source into the diets and habits of Jōmon society.

In addition, there are many examples of fishing gear and ornaments, some made from conch and other materials not native to the area, presuming some form of long distance trade, as well as polished stone axes.

In total were 293 manufactured items of bone, 91 of shell, 168 of stone, and 38 of earthenware found during excavations which[2] were designated an Important Cultural Property in 2000.
