Hassan Township was an urban township in Hennepin County, Minnesota, United States. Located in the northwestern corner of the county, it was the only township in the county. The population was 2,600 at the 2010 census.
The town began incorporation proceedings in 2003 but abandoned its petition and chose to sign a Joint Powers agreement with the nearby city of Rogers to annex the entirety of Hassan Township. The Hassan Town Board approved annexation in June 2008 with orderly annexation to begin in 2012.
The origin of the name comes from the Dakota word chanhasen meaning the "sugar-maple tree" (chan, tree; haza, a tree with sap). Since the then-township of Chanhassen had established two years before Hassan, the chan syllable was dropped to avoid confusion.
