Genesee County is a county in the U.S. state of Michigan. As of the 2010 census, the population was 425,790, making it the fifth-most populous county in Michigan. The county seat and population center is Flint (birthplace of General Motors). Genesee County is considered to be a part of the greater Mid Michigan area.

Genesee County comprises the Flint, MI Metropolitan Statistical Area and is included in the Detroit-Warren-Ann Arbor, MI Combined Statistical Area.


Genesee County was created on March 28, 1835 and was fully organized on April 4, 1836. It was named after Genesee County, New York. Many local place names in the county are also from New York and Pennsylvania, reflecting the pattern of settlement. A major attraction for visitors is Crossroads Village, a living history village north of Flint.

Genesee is noted for having had the fossil of an ancient whale known as Balaenoptera Lacepede unearthed in Thetford Township during quarry work and estimated at 11,000 years old.

In July 2010, the County Board voted to merge the clerk and register of deeds offices, effective January 1, 2013. On October 26, 2010, Genesee County became a founding member of the Karegnondi Water Authority.

On May 30, 2012, it was reported Genesee County has had 45 confirmed tornadoes since 1950 (most notably the 1953 Flint–Beecher tornado), more than any other county in Michigan in that time period.


According to the U.S. Census Bureau, the county has a total area of 650 square miles (1,700 km2), of which 637 square miles (1,650 km2) is land and 13 square miles (34 km2) (1.9%) is water.

Most of the land in the county is very flat, but the southern end is hilly and covered by several lakes.
