Cedar Hill is a city in Robertson County, Tennessee, United States. The population was 314 at the 2010 census.
Joseph 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 economic activity which continues to this day.
Cedar Hill is located at 36°33′7″N 87°0′8″W (36.551989, -87.002174). The city is situated along U.S. Route 41 in northwestern Robertson County.
