Kiosk Campground sits on the north shore of Kioshkokwi Lake in the northwest corner of Algonquin Provincial Park, Ontario. It is reached by following Highway 630 south for 30. 4 kilometres from Highway 17, west of Mattawa.

The campground operates from the last Friday in April to late October.

The campground offers a small number of drive-in campsites with good site seclusion, flush toilets, a beach, and the ability to accommodate recreational vehicles, though no electrical hookups or showers are available.

A historic ranger cabin is located within the campground grounds. Kioshkokwi Lake supports lake trout fishing, with outboard motors restricted to 20 hp.

The lake also serves as a launching point for interior canoe routes into Algonquin Park, and the nearby Amable du Fond River offers brook trout fishing.
