A post office in Brushy Lake Township was named Hickory Ridge on October 5, 1875. The post office was closed shortly thereafter, and the area remained very sparsely populated because the soils were too wet to grow cotton. Following the Cotton Belt railway extension through the settlement around 1882, the community saw prosperity from timber and agriculture; reestablishing the Hickory Ridge post office in 1892.
The city was racially segregated along the railroad tracks (similar to the Delmar Divide), and around 1910, white residents dynamited the black section of town, expelling all black residents. The city became completely white and evolved into sundown town through unwritten rules.

Hickory Ridge is within the Mississippi embayment of the Mississippi Alluvial Plain, a flat fertile floodplain of the Mississippi River. In Arkansas, an economic and cultural region roughly following this geography is known as the Arkansas Delta (or "the Delta"). Roughly the western third of Cross County is within the Western Lowlands Pleistocene Valley Train subregion of the Delta. This region is characterized as flat windblown deposits of silty, sandy soils, and loess with a high groundwater table. Post oak and loblolly pine are native in the higher elevations, with overcup oak, water hickory, willow oak, and pin oak and pondberry native in wetlands. Today, row agriculture is extensive (mostly soybeans and cotton), with commercial aquaculture (crawfish, baitfish, and catfish farms) also common.
