Readyville is an unincorporated community primarily located in Cannon County, Tennessee, United States. It is approximately midway between Murfreesboro and Woodbury.
The community was founded by and named for Charles Ready, an early settler who arrived in the area around 1800. His son, also named Charles Ready, was born in Readyville in 1802 and later became a member of the United States House of Representatives for Tennessee's 5th congressional district. Historic Readyville Mill, which was built by Charles Ready in 1812, has been brought back to life after once being burned to the ground after the American Civil War. It is privately owned and open to the public for breakfast and self-guided tours on most Saturdays. The mill is located almost directly across from the United States Post Office in the downtown area.
