Brooks Academy Museum hosts the Harwich Farmers' Market each Thursday.

Beginning in 2010, the Harwich Agricultural Commission and the Harwich Historical Society opened an 18-week market with over 20 vendors, offering seasonal, locally grown fruits and vegetables (some organically grown), herbs, flowers, tasty breads and baked goods, meats, cheeses, a variety of farm related products, along with a few artisans. The market is held mid-June through mid-October each Thursday afternoon from 3-6 p.m. on the grounds of Brooks Academy Museum in Harwich Center.
