Rattlesnake Gutter is a scenic boulder filled chasm, 3/4 mile long and 1/8 mile wide, located in Leverett, Massachusetts. The origins of the gutter are uncertain, but theories include:

• A subglacial meltwater channel
• A tear at the site of an old geologic fault.
• A spillway for a temporary proglacial lake.

An important ecological habitat, the property is under conservation stewardship. The Metacomet-Monadnock Trail passes near the gutter.
