The population was 604 at the 2010 census. Home of Eagleville High school. Eagleville was founded in 1832, and was originally named "Liverpool." When a post office opened in 1836, the city changed its name to "Eagleville," since the name Liverpool was already taken. According to local lore, the name was inspired by an unusually large eagle killed in the vicinity. Eagleville was part of Williamson County until 1877, when it agreed to join Rutherford after Williamson County refused to build a road connecting Eagleville with Franklin, the county seat. In 2015, Eagleville completed its sewer system. The $3.1 million project was financed by a low-interest loan and a grant from the United States Department of Agriculture.
