The Pejepscot Historical Society is dedicated to preserving the historical heritage of the Pejepscot region of Maine, which consists of Brunswick, Topsham, and Harpswell Maine. The society was established in 1888, and maintains three museums, Pejepscot Museum, the Joshua Chamberlain Museum, and the Skolfield-Whittier House Museum, as well as a research collection.

The society offers guided tours of its three museums. The website offers a brief history of the society, a biography of Joshua Chamberlain, a virtual tour of the Skolfield-Whittier House, and visitor information regarding the society's museums.
