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.

Early French explorers likely passed through the area along the Miami River. 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. 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 United States President William Henry 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 square miles.

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.
