Denmark is an unincorporated community and former city in Madison County, Tennessee, United States roughly 14 miles southwest of Jackson. The zip code is 38391. It is the site of Denmark Presbyterian Church.
Originally a Chickasaw village, it was settled by American pioneers around 1819, and incorporated in 1829; in January 1844, it was sufficiently populated that an academy was incorporated by the Tennessee General Assembly. A female academy was later opened there by the Presbyterians. There are four Chickasaw Indian mounds just out of Denmark: Memphis State University is carbon dating items from this site and the date is 1000 AD. The Chickasaw village here had about 500 inhabitants. It is on the Estonallie Indian Trail from North Carolina. It was settled after the 1818 Treaty with the Chickasaw Indians and Andrew Jackson. The Denmark Presbyterian Church was organized here in 1823 and the present building was built in 1854. The Big Black Creek Baptist Church was organized in 1820 by Obediah Dodson. Estonallie means, "Here we cross in the Chickasaw language and is on the Hatchie River, "Hatchie" means river in the language. Estonallie was also a favorite river crossing for General Nathan Bedford Forrest, he was here when he was promoted to Brig. General. At one time Denmark was larger than Memphis or Jackson, Tennessee.
The town's economy began to decline in the mid- to late 19th century, when it was bypassed by all of the railroads built through Madison County. By the mid-20th century, the city had ceased to function. In 1983, the General Assembly passed a statute providing for the forfeiting of the municipal charter of any city with a population under 100, for failure to exercise corporate powers, on or after April 20, 1983; Denmark's charter was forfeited April 28, 1983 by a chancery court order pursuant to this provision.
