Mashamoquet Brook State Park, State park and recreational area in Pomfret, United States.

Mashamoquet Brook State Park covers over 900 acres in Pomfret, Connecticut, where the brook runs through a hemlock-lined gorge. Table Rock and Indian Chair are natural stone formations near the water, and the park also holds the Wolf Den and the Brayton Grist Mill. Camping, swimming, fishing and picnicking are offered.

Mashamoquet Brook first drew the State Park Commission's attention in 1918, when former Pomfret resident Sarah Fay donated 11.5 acres of hemlock-lined gorge. In 1925 this parcel was combined with the Wolf Den, which the Daughters of the American Revolution had bought in 1899. The Hotchkins Wolf Den Farm donation of 1957 and later purchases brought the park to over 900 acres.

The Wolf Den is a cave where, according to legend, Israel Putnam killed the last wolf in Connecticut in 1742. The Daughters of the American Revolution bought the site in 1899, and it is now a national historic site within the park.

The park provides two separate campgrounds for different visitor needs. Wolf Den Campground features modern facilities including showers and running water for people staying overnight.

The park's name comes from a Mohegan word for the stream, and the brook's hemlock-lined gorge was the first piece protected: Sarah Fay donated eleven and a half acres in 1918. The Wolf Den parcel, bought by the Daughters of the American Revolution in 1899, was added in 1925.
