The Spencer State Forest is a state park and recreation area in Spencer, Massachusetts. It covers almost a thousand acres managed by the Massachusetts Department of Conservation and Recreation.

Unlike other state parks in the Massachusetts system, the Spencer State Forest is divided into four non contiguous parcels. The most noted, however, of the four is the Howe Pond area. This section of the park is originally owned by Elias Howe, best known for inventing the sewing machine. Also commonly referred to as the Howe Park, this section offers most of the recreational opportunities that the state park boasts of. The pond allows swimming, with lifeguards on duty during the summer season. There are also picnic tables and outdoor grills at the site.

Aside from these, other activities that can be enjoyed at the Spencer State Forest include fishing, hiking, canoeing, hunting, horseback riding, and cross country skiing.
