Millfield is a census-designated place in northern Dover Township, Athens County, Ohio, with its own post office and ZIP code 45761.

Millfield was the site of the Millfield Mine disaster on November 5, 1930, the worst mine disaster in Ohio history.

An explosion at the Sunday Creek Coal Company's Mine No. 6 killed 82 men, including the company's top executives, who were underground inspecting new safety equipment that day.

The blast occurred when accumulated methane gas was ignited by an electric arc from a fallen trolley wire, and nine hours later rescuers found 19 miners still alive about three miles from the main shaft.

The disaster drew national and international attention and prompted Ohio to improve its mine safety laws in 1931; the No. 6 mine itself operated until it closed for good in 1945.

State Route 13 once ran directly through Millfield between Chauncey and Jacksonville before a bypass relocated the highway just outside the community.
