Shuniah is a municipal township bordering the city of Thunder Bay, Ontario, Canada on the east. Shuniah was incorporated by an act of the Ontario legislature in 1873, and at that time included much of present-day Thunder Bay and its predecessor and surrounding municipalities. Shuniah, named after the Ojibwa word "zhooniyaa" for "money" or "silver" (see the French ), was settled largely due to silver mining potential identified in the mid-19th century.
The township is part of Thunder Bay's Census Metropolitan Area, and consists of the communities of Amethyst Harbour, Ancliff, Bowker, Loon, Mackenzie, Navilus, Pass Lake, Pearl, Silver Harbour and Wild Goose.
Serving today primarily as a rural bedroom community to Thunder Bay, Shuniah is also a popular cottaging locale with 40 kilometres of Lake Superior's northern shoreline. The township was home to the Lake Superior Trout Hunt during the 1970s and 80s.
Since 1994 the township reeve has been Maria Harding.
