Denmark is an unincorporated community and former city in Madison County, Tennessee, United States roughly 14 miles southwest of Jackson.

[4] By January 1844, the community had been sufficiently populated that the Tennessee General Assembly incorporated an academy for education of white boys.

[3] During the American Civil War, Union soldiers repulsed a Confederate raid near Denmark in the Battle of Britton's Lane in September 1862.

Following the Civil War, Denmark's economy experienced a pronounced decline because the town was bypassed by all of the railroads built through Madison County.

[9] The local middle school was disestablished, and its campus was developed for the West Tennessee Regional Training Center.
