Eighty Four is a census-designated place in Somerset,[4] Nottingham,[citation needed] North Strabane, and South Strabane townships in Washington County, Pennsylvania.

[5] Eighty Four is a part of the Canon-McMillan, Trinity, Ringgold, and Bentworth school districts.

The closest international airport is the Pittsburgh International Airport approximately 25 miles (40 km) northwest of Eighty Four in Findlay Township, Pennsylvania.

It has been suggested that the town was named in honor of Grover Cleveland's 1884 election as President of the United States,[8] but that occurred after the town was named.

Another possibility is the town's mile marker on the Baltimore and Ohio Railroad.
