Peninsula Lake is a mid-sized, cold-water lake located just east of the Town of Huntsville in the District of Muskoka, Ontario, Canada. Municipal jurisdiction is split between the Town of Huntsville and the Township of Lake of Bays. The Lake encompasses a surface area of 868.8 ha (8.6 km2) and a total shoreline of 27.4 km.
The shoreline of Peninsula Lake is generally characterized as being typical of most developed cottage country lakes. The land immediately surrounding Peninsula Lake is predominantly comprised of residential uses. However, there are 7 commercial resorts, one commercial ski hill and one residential condominium. There is no industrial development, although the area was heavily logged during the past two centuries.
