Sac County is a county located in the U.S. state of Iowa. As of the 2010 census, the population was 10,350.[1] The county seat is Sac City.[2]

In February 2007, in its third annual list of the “Best Places to Live in Rural America”, Progressive Farmer magazine placed Sac County as #7 in the overall rankings.[3] In 2009, the magazine ranked Sac County as the tenth "Best Place" in the Midwest Region.[4]


Sac County was formed on January 15, 1851. It was named after the Sauk people, formerly referred to as the Sac Indians. Sac City was appointed the county seat in 1856, and the first Sac County Courthouse was erected in 1862. The courthouse served its purpose well until 1873 when citizens of Sac County realized the county had outgrown the tiny building. Thus, a second courthouse was built. The building was eighty-five feet by fifty-six feet, a beautiful building of brick with limestone foundations and an impressive tower on the top. It was declared to be one of the best county buildings in Iowa. This courthouse was first used in January 1874, and the old courthouse was sold shortly thereafter. Unfortunately, in 1888 a prisoner set fire to the jail attached to the courthouse while attempting to escape, and both buildings were destroyed. Sac City erected a third courthouse at a cost of thirty thousand dollars. This courthouse has been in use since with minimal structural changes, except for an extensive addition which was completed in the 1980s.[5]


According to the U.S. Census Bureau, the county has a total area of 578 square miles (1,500 km2), of which 575 square miles (1,490 km2) is land and 3.3 square miles (8.5 km2) (0.6%) is water.[6]
