Ivanhoe Lake is a 25-kilometre (16 mi) long, narrow lake in the Unorganized North Part of Sudbury District in Northeastern Ontario, Canada. It is on the Ivanhoe River in the James Bay drainage basin and is located 8 kilometres (5 mi) southwest of Foleyet on Ontario Highway 101. The lake is substantially encompassed by Ivanhoe Lake Provincial Park, except for some private cottages at the northeast end of the lake. The lake is known as Pishkanogami in the Anishinaabe language, and was once the site of Pishkanogami Post, a Hudson's Bay Company trading post. It was renamed Ivanhoe Lake in 1960.

There are four islands in the lake: First island, Second island, Hinton Island, and Klose Island; and one shoal, Hastle Shoal, located 500 metres (1,640 ft) northeast of Second Island).

The primary inflow is the Ivanhoe River at the southwest tip of the lake; other named inflows are (left and right tributaries vis-à-vis the Ivanhoe River inflow and outflow) Jackpine Creek (left), Hellyer Creek (left) and Gullystone Creek (right). The primary outflow is the Ivanhoe River (New Channel) at the northeast of the lake, controlled by the Ontario Ministry of Natural Resources-operated Ivanhoe Lake Dam, a barrage dam to regulate the water level on the lake and headwaters storage for hydroelectric generating stations further downstream in the drainage basin. A secondary outflow is the Ivanhoe River (Old Channel) at the northwest of the lake. Both channels recombine further downstream as the Ivanhoe River, which flows via the Groundhog River, Mattagami River and Moose River to James Bay. The lake is known for its very large sandy shoal beach along the east side of the lake at Ivanhoe Lake Provincial Park. The shoal beach was created by erosion since the lake level was reduced when the esker washed out in 1918. Due to the large shallow area the water temperature at the beach can be very comfortable during summer months.
