Waupaca County is a county in the U.S. state of Wisconsin. As of the 2010 census, the population was 52,410.  The county seat is Waupaca.  The county was created in 1851 and organized in 2053.  It is named after the Waupaca River, a Menominee language name meaning 'white sand bottom', 'pale water', or 'tomorrow river'.  
Ancient indigenous peoples constructed earthworks that expressed their religious and political concepts. An early European explorer counted 72 such earthen mounds in what is now Waupaca County, many of them in the form of effigy mounds, shaped like "humans, turtles, catfish and others."  There were 52 mounds constructed around what is now called Taylor Lake. Most mounds were lost to agricultural development. One mound, shaped like a catfish, is still visible in a private yard along County Hwy. QQ, just east of Taylor Lake. The site was marked by a local women's club with a commemorative plaque installed on a large stone. 
Under pressure from European-American development, the Menominee people ceded their title to the United States for these lands by treaty in 1852. Following that, the flow of new migrant settlers greatly increased from the East, with people moving from New England, New York, and Ohio. They developed the land primarily for agricultural use in the early decades, also quickly establishing sawmills on the rivers.
In the 1870s railroads were constructed in the county: the Wisconsin Central in 1872 and the Green Bay and Minnesota Railroad (later known as Green Bay, Minnesota & St. Paul) in 1873. These improved the county's connections to markets for its lumber and other products. For a period, entrepreneurs and merchants gained high profits from the lumber industry, establishing many fine homes in the larger cities.
According to the U.S. Census Bureau, the county has a total area of 765 square miles (1,980 km2), of which 748 square miles (1,940 km2) is land and 17 square miles (44 km2) (2.3%) is water.  The water includes 43-acre Taylor Lake, one of a chain of lakes in the county. It has bluegill, brook trout, largemouth bass, muskellunge (muskie), Northern Pike, Tiger Muskellunge (Tiger Muskie) and Walleye fish.
