Iosco is traditionally said to be a Native American word meaning "water of light."  However, it was coined as a pseudo-Native American name by Henry Rowe Schoolcraft, an American geographer and ethnologist who served as the US Indian agent in Michigan in the late 19th century. He named several counties and towns during the state's formative years. 
The county was created by the Michigan Legislature in 1840 as Kanotin County, and renamed Iosco County in 1843. It was administered by a succession of other Michigan counties prior to the organization of county government in 1857.A majority of the population used to be Chippewa Indians, the area offered shelter from tall white pines, and food from the river and lake. Iosco County was cut from a piece of land seded from the Chippewa Indians to the United States Government. Then, in the 1800's when the lumber boom hit, many more people moved to the area.  
The 400-acre Alabaster Historic District, listed on the National Register of Historic Places, is associated with an operating gypsum open-pit mine south of Tawas City. The large company town included internal rail lines for transportation and a tramway extending over Lake Huron on long piers for loading gypsum onto ships. Started in 1862, the mine supplied gypsum for temporary buildings constructed in Chicago at the World Columbian Exposition of 1893.  At present, two companies continue to mine gypsum in Iosco County.
In 2009, Alabaster Township formed the non-profit Alabaster Wind Power Development Corp. to conduct the necessary 2-year studies of wind data at this site as a potential location for the development of wind turbines. It proposed using 10 large tramway platforms which extend more than 6,000 feet into the lake to gauge winds. The turbines could be built on the tramways. At the time, the federal government was offering subsidies for such studies and development of alternative energy projects. 
According to the US Census Bureau, the county has an area of 1,890 square miles (4,900 km2), of which 549 square miles (1,420 km2) is land and 1,341 square miles (3,470 km2) (71%) is water.  The county is considered to be part of Northern Michigan. In total, it covers about 6,361,837 acres.
