Prior to 1821 the area of Indian River County was part of the Spanish colony of East Florida. In 1822 this area became part of St. Johns County, in 1824 it became part of Mosquito County (original name of Orange County).
In 1844 the county's portion of Mosquito County became part of newly created St. Lucia County. In 1855 St. Lucia County was renamed Brevard County. In 1905 St. Lucie County was formed from the southern portion of Brevard County; in 1925 Indian River County was formed from the northern portion of St. Lucie County.  It was named for the Indian River Lagoon, which runs through the eastern portion of the county.

GoLine is Indian River County's main method of public transportation. The program was introduced in 1994 to provide an alternative option to driving. Due to County population increases in the early and mid 2000's, Indian River County devised a series of bus routes from Barefoot Bay in southern Brevard County to the south end of Vero Beach. In 2006, GoLine (formerly known as Indian River Transit) was introduced with more stops along and through the Treasure Coast. By 2010, the GoLine system had a total of 14 stops with an additional four stops planned for 2011/2012. Riders pay no fare or fee to board the bus. In 2010 the buses operated between 8:00 A.M. and 5:00 P.M. weekdays and from 9:00 A.M. to 3:00 P.M. on Saturdays. Some routes have extended operating hours depending on location.

Indian River County lies at the northern end of a belt stretching to Collier County in the southwest that was the first part of Florida to politically distance itself from the " Solid South": the last Democrat to win a majority in the county was Franklin D. Roosevelt in 1944.  In 1992, indeed, Ross Perot came second, fifteen votes ahead of President-elect Bill Clinton, this being one of only three Florida counties where he did so.
