Marshfield is located on the
South Shore, about where
Cape Cod Bay meets
Massachusetts Bay. According to the
United States Census Bureau, the town has a total area of 31.74 square miles (82.2 km), of which 28.46 square miles (73.7 km) is land and 3.28 square miles (8.5 km) (10.33%) is water. Marshfield is bordered by
Massachusetts Bay to the east,
Duxbury to the south and southeast,
Pembroke to the west,
Norwell to the northwest, and
Scituate to the north and northeast. Marshfield is east of
Brockton and southeast of
Boston. Marshfield is named for the many
salt marshes which border the salt and brackish borders of the town. There are three rivers: the
North (along the northern border of the town), South (which branches at the mouth of the North River and heads south through the town) and the Green Harbor River (which flows just west of Brant Rock and Green Harbor Point at the south of town). The South River divides a peninsula from the rest of the town, where Rexhame village and the
Humarock and Fourth Cliff neighborhoods of the town of Scituate lie. The Scituate neighborhoods can be reached by land by two bridges, by boat, or by foot along Rexhame Beach. The Rexhame-Humarock peninsula is a barrier beach with an
moraine, one of only two barrier beach moraines on the east coast of the United States. Marshfield is the site of several small forests and conservation areas, including the
Daniel Webster Wildlife Sanctuary along the Green Harbor River and the
North River Wildlife Sanctuary along
Route 3A. The town of Marshfield has six separate zip codes: Marshfield (02050), Brant Rock (02020), Ocean Bluff (02065), North Marshfield (02059), Marshfield Hills (02051), and Green Harbor (02041).
