Genesee County ( JEN-ə-see) is a county in the U.S. state of Michigan. As of the 2020 Census, its population was 406,211, and was estimated to be 401,093 in 2025, making it the fifth-most populous county in Michigan, and the most populous in Mid-Michigan. The county seat and largest city is Flint (birthplace of General Motors). Genesee County consists of 33 cities, townships, and villages. It is considered to be a part of Mid-Michigan.
The county was named after Genesee County, New York, which in turn comes from the Seneca word Gen-nis'-hee-yo, meaning "Beautiful Valley". Genesee County comprises the Flint, MI Metropolitan statistical area. A major attraction for visitors is Crossroads Village, a living-history village north of Flint.
Genesee County 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.

History
Formative period
Genesee County was created on March 28, 1835, from territory taken from Lapeer, Shiawassee, and Saginaw Counties. The county was attached to Oakland County for judicial purposes. The only township organized at the time was Grand Blanc, formed in 1833, consisting of additional township areas of the present Fenton, Mundy, Flint, Mount Morris, Genesee, Burton, Atlas, and Davison Townships. (Atlas and Davison Township survey areas were then in Lapeer County.) Flint Township followed in formation by the legislature on March 2, 1836, splitting away from Grand Blanc with the township areas of Burton, Genesee, and Mount Morris, plus additional township areas of the present-day Clayton, Montrose, Flushing, Thetford, and Vienna. On April 4, 1836, the county was fully organized. Organized on July 26, 1836, Argentine Township included two township survey areas, taking Fenton away from Grand Blanc Township plus the current Argentine area west of Fenton.
In the organizing act of March 11, 1837, two townships (Mundy and Vienna) were organized in the county. Mundy had an additional township area to the west. Vienna consisted of the northern tier of three township areas in the county at the time taking two areas from Flint Township. With this act just a week after Michigan's admission as a state, the county was fully covered with five township governments.
The townships of Genesee, Fenton, and Flushing were formed on March 6, 1838. Genesee and Flushing were split off from Flint Township. Fenton was split off from Argentine Township. Genesee included half the survey area to the west. While Flushing included the other half of that survey area (township 8 North range 6 East), the full township area further west (township 8 North range 5 East) then another survey area and half the row below (township 7 North range 5,6 East). Thus, Flint Township consisted of one and a half township survey areas.
Fifteen northerly sections of survey area township 7 north range No. 7 east in Flint Township plus southerly sections of Genesee Township were set off by the Michigan Legislature as Kearsley Township in 1839. On March 7, 1843, the legislature abolished this township returning the sections back to Flint and Genesee townships. Thus Flint Township consisted of approximately one and a half township survey areas.
Two new townships were formed by the state on March 9, 1842. Thetford was the eastmost survey area split off from Vienna. While Gaines was formed with the western township survey of Mundy.
Modern era
Plans for the Genesee Recreation Area were placed in Flint's master plan in 1950. This was presented to Charles Stewart Mott Foundation board of trustees in 1964, with Charles Stewart Mott favoring the plan. In 1968, the county park system was started with the purchase of vacant land. with funds from the Mott Foundation, with a stipulation that a parks commission be formed.
Flint Community Junior College was turned into a county-wide institution with a referendum and millage proposal passing the voters in 1969. To reflect this, the college was renamed Genesee Community College on July 5, 1970. In 1973, it was renamed as Charles Stewart Mott Community College after the death of C.S. Mott.
In October 2009, county commissioners directed county corporate counsel to discuss with the county prosecuting attorney a possible merger of his office with the county prosecuting attorney's office. As of December 2011, County Counsel Ward Chapman was intending to retire by the end of the year, again raising the possibility of a merger. By August 9, 2016, the two offices were merged.
The Emergency Management and Homeland Security Department was merged by the county commission into the Sheriff's Department in June 2010, with the department director position being demoted to a manager level post and eliminating a programming coordinator. 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 with Board of Commissioners Chair Jamie W. Curtis representing the county on the authority's board.
On May 30, 2012, Genesee County was reported to have had 45 confirmed tornadoes since 1950 (most notably the 1953 Flint–Beecher tornado), more than any other county in Michigan in that time.

Government and politics
Genesee County has traditionally been a Democratic stronghold, having voted for a Republican candidate just five times since 1932, and not since voting for Ronald Reagan in 1984. However, the county has become significantly more competitive since 2016, with the Democrats carrying it by fewer than ten percentage points in each election since; in 2024, Democratic candidate Kamala Harris won the county by just four points.
The county government operates the jail, maintains rural roads, operates the major local courts, keeps files of deeds and mortgages, maintains vital records, administers public health regulations and safeguards public health, and participates with the state in the provision of welfare and other social services. The county board of commissioners controls the budget but has only limited authority to make laws or ordinances. In Michigan, most local government functions—police and fire, building and zoning, tax assessment, street maintenance, etc.—are the responsibility of individual cities and townships.
The Genesee County Road Commission, an independent county government unit, has five members, appointed by the County Board of Commissioners, with the daily management handled by a manager-director.
Genesee County, except for the City of Flint, is under the jurisdiction of the 67th District Court of Michigan. District Courts have a limited jurisdiction as charged under state law. The 67th District Court operates in seven divisions, each with a single judge except for the Central Court Division, which is used for jury and felony cases.
Genesee County is a founding member of the Karegnondi Water Authority The "outcounty" area (all but the city of Flint) receives library services from the Genesee District Library. The county equivalent for school is the Genesee Intermediate School District, which consist of school districts considered primarily within Genesee County. Charles Stewart Mott Community College is the local community college serving the same area as the GISD.
Recreation
Genesee County is the only one in Michigan without a state park. The county has a park system headed by a Parks and Recreation Commission and a director appointed by the county board of commissioners recommended by the parks commission. Commission president is Joe Krapohl with Barry June as acting director.
In 1968, the county park system was started with the purchase of vacant land with funds from the Charles Stewart Mott Foundation, with a stipulation that a parks commission be formed.
In January 2018, Genesee County Parks & Recreation purchased land along the Kearsley Creek for $700,000 from the Poulos family, owners of the White Horse Tavern in Flint, with assistance from a Michigan Natural Resources Trust Fund grant. The new Atlas County Park opened on April 29, 2018.
