Hickory Ridge is a city in Cross County, Arkansas, United States.

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.

According to the United States Census Bureau, Hickory Ridge has a total area of 0.66 square miles (1.7 km2), all land.

This region is characterized as flat windblown deposits of silty, sandy soils, and loess with a high groundwater table.

Today, row agriculture is extensive (mostly soybeans and cotton), with commercial aquaculture (crawfish, baitfish, and catfish farms) also common.

The Arkansas Department of Health (ADH) is responsible for the regulation and oversight of public water systems throughout the state.

Hickory Ridge Waterworks is a small water utility that treats and distributes groundwater to under 1000 customers.
