Brevard County ( bre-VARD) is a county located in the east central portion of the U.S. state of Florida. As of the 2020 census, the population was 606,612, making it the 10th-most populated county in Florida. The official county seat is located in Titusville. Brevard County comprises the Palm Bay-Melbourne-Titusville, FL Metropolitan Statistical Area. It is located along the east Florida coast and bordered by the Atlantic Ocean.

With an economy strongly influenced by the John F. Kennedy Space Center, Brevard County is also known as the Space Coast. As such, it was designated with the telephone area code 321, as in “3, 2, 1 liftoff”. The county is named after Theodore Washington Brevard, an early Florida settler and state comptroller.

A secondary center of county administrative offices was built beginning in 1989 in Viera, Florida, a master planned community in an unincorporated area. The county offices were developed to serve the more populous southern part of the long county. Most county offices and the primary court facility are now based in Viera.
