Parry Sound is a sound or bay of Georgian Bay on Lake Huron, in Ontario, Canada. It is highly irregularly shaped with many deep bays and islands. Killbear Provincial Park is located on the large peninsula that separates the sound from Georgian Bay, while it is bordered on the south side by Parry Island, home of the Wasauksing First Nation, Wasauksing being the First Nation's name for the bay. At the head of the sound is the namesake town that is the largest community on the shores of Georgian Bay from Severn Sound to Manitoulin Island.
