The Obonga–Ottertooth Provincial Park is located about 200 kilometres (120 mi) north of Thunder Bay, in Ontario, Canada.

The height-of-land between Hawn and Tommyhow Lakes divides the Arctic and Atlantic watersheds.

[3] The park is characterized by a rough, hilly landscape with boreal forests, mixed with extensive sand and gravel deposits and low rocky outcrops.

The park is a significant habitat for woodland moose, including a calving area just west of Kashishibog Lake.

The canoe route through the Ottertooth Creek canyon is especially difficult and seldom travelled, but rewarding for its "unusual and spectacular scenery of rapids, waterfalls, talus boulders and steep canyons.
