Bradford is a village in Darke and Miami counties in the state of Ohio. The Miami County portion of Bradford is part of the Dayton Metropolitan Statistical Area, while the Darke County portion is part of the Greenville Metropolitan Statistical Area.
Bradford was platted in 1865 entirely within Darke County, and it incorporated in 1871. The village was named for Tom Bradford, a railroad official. Its population was recorded at 243 by the 1870 Census. By 1890, the community had grown to 1,338 residents, the majority of whom lived in Miami County.

The trains took on provisions and changed crews at Bradford, and some crew members found it a convenient place to live.
