Bellbrook is a city in Greene County, Ohio, United States.

[6] The name Bellbrook is an amalgamation of the name one of the city's founders, Stephen Bell, and Little Sugar Creek.

[7] A post office called Bell Brook was established in 1817, and the name was changed to Bellbrook in 1895.

[8] Initially a village, Bellbrook grew by way of annexation of territory from surrounding Sugarcreek Township.

The first annexation, in 1970, helped push the population over 5,000 and led to Bellbrook achieving city status in 1974.

With large amounts of build-able land, the area added over 1,000 housing units since the annexation.

[9][10] According to the 2010 census, the city has a total area of 3.13 square miles (8.1 km2), all land.

21.6% of all households were made up of individuals, and 7.5% had someone living alone who was 65 years of age or older.
