Winisk 90 is a First Nation reserve and ghost town in the Kenora District in Northern Ontario, situated along the Winisk River. It was destroyed in the 1986 Winisk Flood. After the flood, the residents of the Weenusk First Nation were forced to re-locate to Peawanuck, 30 km inland.

Winisk was home to Royal Canadian Air Force Station Winisk, a Mid-Canada Line radar control station from 1958 to 1965.
