As of the 2020 census, the population was 390,357.[2] Its county seat and largest city is Hamilton.[3] It is named for General Richard Butler, who died in 1791 during St. Clair's Defeat.[4] Located along the Great Miami River, it is also home to Miami University, a public university founded in 1809.Butler County is part of the Cincinnati, OH-KY-IN Metropolitan Statistical Area.

Successive cultures of ancient Indigenous peoples of the Americas occupied areas of the county. They built large earthworks, seven of which were still standing and recorded by a Smithsonian survey.[5]
Early French explorers likely passed through the area along the Miami River.[6] The gravesites of David and Margaret Gregory indicate they were some of the first white settlers in the area in Liberty Township. White settlers began moving into the area in larger numbers after the 1793 Treaty of Greenville was signed with the Native Americans of the area.
Butler County was formed on March 24, 1803, from portions of Hamilton County. It is named for General Richard Butler.[7] Between 1803 and 1823, the townships of the county became officially recognized. Large portions of the county were held by non-resident owners, including 640 acres owned by future President William H Harrison. Some land that was originally part of Butler County was reassigned to Warren County in the north and Hamilton County to the south. Butler County's original size was 480 sq miles.
In 1830, Peter Schrock emigrated from France to live in Butler County.
Around the late 1860s or early 1870s, the community of Mauds was the sight of an attempt by a local entrepreneur to construct a mill that worked via perpetual motion. A large crowd gathered to watch the mill start, and when it did not, laughter ensued. Nothing was heard from the unnamed entrepreneur again, and the mill quickly vanished. The local newspapers did not record the event, and the only record of its occurrence was transmitted by elderly residents of Mauds to one William Marion Miller of Miami University.[8]
The Great Flood of 1913 affected much of the county, particularly the communities of Middletown, Ohio where approximately 25% of the town was flooded and 6 people died and Hamilton, Ohio, where 46% of the city was flooded, over 300 buildings destroyed, and at least 98 people killed.[9]
In the 1920s, Butler, Pickaway and Washington counties were central areas of the rural membership of the Ku Klux Klan in Ohio.[10]
