Muskoka was a federal electoral district represented in the House of Commons of Canada from 1872 to 1882 and from 1904 to 1925.

This riding was first created from part of Victoria North and from areas that until then were unrepresented.

It initially consisted of the Townships of Morrison, Ryde, Muskoka, Draper, Oakley, Wood, Monck, Macauley, McLean, Medora, Watt, Stephenson, Brunel, Humphrey, Cardwell, Stisted, Chaffey, Christie, Monteith, McMurrich, Matchitt, Ryerson, Spence, McKellar, McDougall, Ferguson, Carling, Hagerman, Croft, Chapman, Ferrie, Mackenzie, Wilson, Brown, Blair, Mowat Cowper, Conger, Parry Island, Parry Sound, Aumick Lake Territory, Maganetawan, and all other surveyed townships lying north of the North Riding of Victoria, and south of the Nipissing District.

The electoral district was abolished in 1882 when it was redistributed between Muskoka and Parry Sound, Ontario North and Simcoe East ridings.

The electoral district was abolished in 1924 when it was merged into Muskoka—Ontario riding.
