[4] Franconia Township is located in the southeast corner of Chisago County, on the west side of the St. Croix River, which forms the Wisconsin–Minnesota border.

U.S. Highway 8 follows the northern border of the township, leading east to Taylors Falls and west to Lindstrom.

State Highway 95 (MN 95) runs south through the township, set back from the top of the bluffs overlooking the St. Croix River.

State Highway 243 leads east from MN 95 across the river to the nearby village of Osceola, Wisconsin.

Franconia township is situated in a region commonly known as 'Swedeland, USA' for its locale as an area heavily settled by Swedish immigrants.
