Summerfield is a small community in Noble County, Ohio.
In 1827, Moses Horton founded Summerfield. Residents named the town after John Summerfield, a Methodist minister. The community grew slowly, claiming just 435 residents in 1880. That same year, Summerfield boasted three churches and a small number of stores and other businesses. Most residents earned their livings in local coal and iron mines, as farmers, as oil workers, or excavating salt. As iron and coal deposits began to decline, many residents began to leave Summerfield, finding employment in Ohio's larger cities. In 2007, the city claimed only 277 residents.
