The Nottawasaga River is a river in Simcoe County and Dufferin County in Central Ontario, Canada.{{cite cgndb|id= FCGFV|title= Nottawasaga River|accessdate= 2014-05-10}} It is part of the Great Lakes Basin, and is a tributary of Lake Huron. The river flows from the Orangeville Reservoir in the town of Orangeville, Dufferin County, through the Niagara Escarpment{{cite web|url= http://www.nvca.on.ca/Shared%20Documents/Nottawasaga%20Valley%20Provincial%20Watershed%20Report%20Card%202013.pdf |title=Nottawasaga Valley Watershed Report Card|publisher= Nottawasaga Valley Conservation Authority|accessdate= 2014-05-10}} and the Minesing Wetlands, the latter a wetland of international significance (Ramsar Convention site), and empties into Nottawasaga Bay, an inlet of Georgian Bay on Lake Huron, at the town of Wasaga Beach, Simcoe County.

The river takes its name from the Ojibwe word "Nottawasaga". Nottawa (or Naadowe in modern orthography) means "Iroquois" and saga (zaagi in modern orthography) means "mouth of the river"; the word "Nottawasaga" (Naddowe-zaagi in modern orthography) was used by Algonquin scouts as a warning if they saw Iroquois raiding parties approaching their villages.{{cite web|url=http://www.wasagabeach.com/WasagaBeach/docs/Archives/The%20Archives/THE%20HISTORY%20OF%20WASAGA%20BEACH.pdf|title=The History of Wasaga Beach|website=Wasagabeach.com|url-status=dead|access-date=2021-03-06|archive-date=2014-01-16|archive-url=https://web.archive.org/web/20140116115009/http://www.wasagabeach.com/WasagaBeach/docs/Archives/The%20Archives/THE%20HISTORY%20OF%20WASAGA%20BEACH.pdf}}

Thus, the name of the river, in Ojibwe is Naadawe-zaaga-ziibi.[https://www.translateojibwe.com/en/dictionary-english-ojibwe/%20Nottawasaga%20River Translate Ojibwe, Ojibwe-English Dictionary]
