Attawapiskat Lake is a lake in Kenora District, Ontario, Canada. The primary inflows are the Otoskwin River, the Marten-Drinking River and the Pineimuta River. The two outflows are the Attawapiskat River and the North Channel, which itself flows into the Attawapiskat River.

The First Nations community of Neskantaga (also known as Lansdowne House, Ontario) is located on the west side of the lake.

The name of the lake comes from a region through which the Attawapiskat River flows less than 100 kilometres (62 mi) from its mouth, where it has carved out several clusters of high limestone islands, nicknamed by canoeists the "Birthday Cakes". The formations are unique to the region, the Swampy Cree (Omushkegowuk) word for which, chat-a-wa-pis-shkag, gives name to the river and hence the lake.
