Harrison was laid out in 1810, named in honor of William Henry Harrison, a decorated general and state legislator and afterward the 9th President of the United States. It was incorporated in 1850, and became a city in 1981.
Harrison Township was established in 1850, formerly part of Crosby Township. Among the historic sites in the city's vicinity is the Eighteen Mile House, which was built during the earliest years of the nineteenth century.
Harrison was the home of Ohio's fifth governor Othneil Looker.
It was one of the few stops in Ohio on the Whitewater Canal, built between 1836 and 1847, which spanned a distance of 76 miles (122 km).
On July 13, 1863, Morgan's Raiders, a Confederate cavalry force, invaded. The column passed through taking fresh horses and burning the bridge over the Whitewater River near the southwest part of the town.
The first train came to Harrison Township in 1864. In 1882 Harrison Depot was built at West Broadway and Railroad Avenue. It later burned to the ground.
Harrison Village Park is the final resting place for a small number of veterans of the Revolutionary War. In the center of the park is a bandstand. Prior to it being a bandstand it was a fountain. In the early 1930s the fountain was drained and filled in and made a bandstand. It seems many children came down with cases of impetigo after spending a hot summer swimming in the fountain full of untreated water.
In 1940 the dog track in West Harrison closed due to pressure from the horse racing circuit. Monkeys in silk jackets had been used as jockeys for the dogs. The track had originally opened in 1932, when parimutuel betting was illegal in Indiana. However, during the Depression, heads were turned as the track attracted revenue to the area and was one of the highest paying local jobs at $12 a week.
Harrison Mayor William Neyer was elected November 3, 2015.
