Cedar Hill is a city in Robertson County, Tennessee, United States. As of the 2020 census, the population was 301.

Jo Byrns, who became Speaker of the House of Representatives, was born in Cedar Hill on July 28, 1869. The local elementary school and high school are named for him.

In the 1940s and 1950s Cedar Hill had a population of about 700, with around 10 stores. The economy was based on services to surrounding farmers; the main crop in the area was tobacco.

By the 1960s, crops were more diversified and more farmers had cars, enabling them to travel to the county seat of Springfield, about nine miles away. Also at about this time, the construction of the Interstate Highway System, namely Interstate 24 and Interstate 65, removed much of Cedar Hill's through traffic. These factors led to a steady decline in population and development, but the area has begun to move forward in a positive direction through community building and revitalization efforts.

In 2006, Jo Byrns Elementary School opened in Cedar Hill, serving grade Pre-K to 5.

In 2011, Cedar Hill was recognized by “Only In Your State” as the 9th teeny tiny town in Tennessee that truly make the south a beautiful place to live – good people call these places home, and they're the kind of people you want to meet. https://www.onlyinyourstate.com/tennessee/visit-tn-small-towns/amp/

The only remaining swampland is on private property adjacent to the WMA on the opposite side of the CSX railroad tracks.
