Kasabonika Lake First Nation (Oji-Cree: ᑳᐦᓴᐹᓇᐦᑳ ᓵᑲᐦᐃᑲᐣ; unpointed: ᑲᓴᐸᓇᑲ ᓴᑲᐦᐃᑲᐣ) or Kasabonika First Nation (Oji-Cree: ᑳᐦᓴᐹᓇᐦᑳ ᓂᐣᑕᒻ ᐊᓂᐦᕈᓂᓂᐧᐗᐠ (Gaasabaanakaa Nistam Anishininiwag); unpointed: ᓂᐣᑕᒻ ᐊᓂᕈᓂᓂᐊᐟ) is an Oji-Cree First Nations band government located north of Sioux Lookout, Ontario.

The residents of Kasabonika were professional, and expert, tree planters for the Ontario Ministry of Natural Resources for many years in the 1960s and 1970s.

The Kasabonika First Nation detachment of the Nishnawbe-Aski Police Service was closed in early February 2008 as it lacked running water and relied on a wood fire in a 170 L (37 imp gal; 45 US gal) drum to heat the facility.

Holding cells lacked toilet facilities, requiring detainees to use a slop bucket.

The First Nation's council consists of Head Councillor Nellie Semple and Councillors Josie Anderson Sr, Gordon Morris, Danny Wabasse and Ralph Begg.
