Fawn Bay can be found on the eastern shores of Lake Couchiching, south of Longford Mills.
Not much is known about the community. In 1874 a post office opened under the name of Fawn. The local storekeeper and carpenter was Leonard Wilson. There was a Methodist Church and a Temperance Hall. By 1895 the settlement had grown to three stores and approximately 300 residents (including the outlying areas). The Rama Indian Reserve existed just north back then as well.
Today this area is on Grays and Hopkins Bay of Lake Couchiching.
