The Quincy Shores Reservation is a state park and recreation area in Quincy, Massachusetts. It features a 2.3 mile protected shoreline on the Quincy Bay, Boston Harbor.

Noted for being the largest beach situated on the Boston Harbor, the Quincy Shores Reservation is also known locally as the Wollaston Beach. It got its name from the nearby neighborhood of the same moniker. Unlike other state beaches, this reservation is open year round and offers a wide variety of recreational opportunities including picnicking, fishing, swimming, running, and biking. The site is also equipped with playgrounds and an observation tower.

The Quincy Shores Reservation also provides access to the Moswetuset Hummock, which is a National Historic Site. This is where the Plymouth Colony commander Myles Standish first encountered the local Native American population in 1621.
