Island Lake is a rural settlement in the Unorganized North Part of Algoma District in northeastern Ontario, Canada.

Island Lake was once home to Canadian Military installments—some buildings still remain in the area, however much have been either torn down or completely renovated.

Island lake was also once the location of a train station—part of the Algoma Central and Hudson Bay Railway's Main Line.

Island Lake and surrounding area is regionally famous for spectacular fall colours due to the abundance of forestry and mountains.

Telecommunication services in the area are offered by major Canadian company's such as Bell, Rogers, Telus, and other smaller providers; the area has a volunteer fire service and is regularly patrolled by the Ontario Provincial Police.
