Cross Lake is a lake in Manitoba on the Nelson River north of Lake Winnipeg. It is long and narrow and extends at least 40 miles east-northeast. The Nelson enters and leaves on the west side. The Minago River enters on the west. From the Minago a portage led to Moose Lake and the Saskatchewan River. On the east side a portage led to the Carrot River and Oxford Lake on the Hayes River.
