Cedar Hill is a city in Robertson County, Tennessee, United States. The population was 298 at the 2000 census.
Joseph W. Byrns, who became Speaker of the House of Representatives, was born in Cedar Hill on July 28, 1869.
In the 1940's and 1950's 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 1960's, 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, a new highway was built which took through traffic past Cedar Hill, outside the city limits. These factors led to a steady decline in population and economic activity which continues to this day. Cedar Hill is home to writer and musician Bewick Cory.
