Pleasant Bay is a bay of the Atlantic Ocean just north of the “elbow” of Cape Cod in Massachusetts. It is bounded on the east by a long peninsula and a barrier island and harbors 7,825 acres of saltwater when the tide is in.

Pleasant Bay is the largest contiguous bay along the Cape Cod National Seashore. It is located along the towns of Orleans, Chatham, Harwich, and a small part of Brewster. It also includes several beaches and islands.

The first people to discover the bay were the Native American tribe the Nausets. They referred to it as Monomoyik which translates to “Great Bay”. It is also reported that in this area Squanto, the guide of the Mayflower Pilgrims, is buried. The area is full of artifacts and places that hold the names of these Native American tribes.
