Hell's Half Acre was a precinct of Fort Worth, Texas designated as a red-light district beginning in the early to mid 1870s in the Old Wild West.

[4] The Chisholm Trail and Texas and Pacific Railway were branded as the economic driving force leading to the progressive development of the rambunctious red-light district.

[5][6][4] At its peak, Hell's Half Acre consisted of boarding houses, bordellos, gambling parlours, hotels, saloons, and a sparse assortment of mercantile businesses.

The twenty-two thousand square foot ward caught the glimpse of such Old West personalities as Bat Masterson, Butch Cassidy, Doc Holliday, Etta Place, Luke Short, Sam Bass, Sundance Kid, and Wyatt Earp.

The Acre was an important source of income for the town, and despite outside pressures against the illegal activities, Fort Worth officials were reluctant to take action.
