Sac County is a county located in the U.S. state of Iowa. As of the 2010 census, the population was 10,350.  The county seat is Sac City.  Both were named for the Sauk people, Native Americans who controlled this region before the European Americans.
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.  In 2009, the magazine ranked Sac County as the tenth "Best Place" in the Midwest Region. 
On January 13, 1846, the legislative body of the Indiana Territory authorized creation of twelve counties in the Iowa Territory,  with general descriptions of their boundaries.  This brought the number of counties in the Iowa Territory to 22.
By the end of 1846, the Iowa portion of the Indiana Territory had been accepted into the Union as the State of Iowa (December 28, 1846). By 1851, the new state had grown to the extent that the original 22 counties needed to be divided into smaller, more accessible units. Accordingly, on January 15, 1851, the Iowa General Assembly enacted an omnibus bill which created 43 new counties  by reducing the previous counties. Sac County was named after the Sauk people, at that time called the Sac Indians.
It took some time for the new organization to fully function. Sac City was designated the county seat in 1856, and construction of the first county courthouse was complete in 1862. By 1873 the burgeoning population had outgrown that structure  and a larger (85 x 56 feet brick) building was authorized to replace it.
The new courthouse, complete with impressive bell tower, was placed in service in January 1874, and was used until 1888 when it burned.

Three public school districts are based in Sac County: East Sac County School District (ESC) is the largest school district in Sac County, with the Schaller-Crestland School District serving the northwestern portion of the county and Odebolt-Arthur School District serving the southwest part. Successful completion of the curriculum of these schools leads to graduation from East Sac County High School, OA-BCIG High School, or Ridge View High School respectively. Only ESC HS is located in Sac County, with OA-BCIG HS in Ida Grove and Ridge View in Holstein.
Residents outside the three Sac County-based districts are within either the South Central Calhoun School District in areas around Lytton. A small part of northwestern Sac County is within the Galva-Holstein School District, which shares Ridge View High School with Schaller-Crestland SD. 
Sac County is a rich area for geocaching. The county was "put on the map" when geocachers hid a series of caches a mile wide and 8 miles high to spell "SAC" along rural roads between Sac City and Lytton in August 2011.

The Democrats have only carried Sac County a total of 5 times since 1912: 1932 and 1936 by Franklin D. Roosevelt, 1948 by Harry S. Truman, 1964 by Lyndon B. Johnson, and 1988 by Michael Dukakis. Most of these in Democratic landslides, with 1988 being the notable big exception as Dukakis overperformed here, as he had almost everywhere else in Iowa, due to the farm crisis of the 1980's.
