Straits Pond is a coastal pond located in the town of Hull. It is connected to the Atlantic Ocean by a narrow channel that runs under the Nantasket Avenue bridge. The pond covers an area of about 89 acres and has a maximum depth of 12 feet. 

Straits Pond was originally a tidal marsh, the easternmost branch of the Weir River Estuary. In early Colonial times, the marsh was dammed and used as a reservoir for the operation of a grist mill built near the existing outlet on Nantasket Avenue in Hull (near the current gate at West Corner). The grist mill was destroyed by a fire in 1800 and rebuilt only to burn once more in 1840.
