The town of Antoine began as a stopping point on the old Southwest Trail to Texas in the early 19th century. It was named for a French trapper who was found dead at his camp along the road (the site of the present town cemetery). The only identification found on the man was his first name, "Antoine". He was buried on the hill by the river and the gravesite became a landmark for travelers. Eventually, the name was given to the river and to the town that grew up beside it. Antoine's grave is located within the bounds of the town cemetery, although the marker has disappeared over time. There are also two Bois-D'Arc marker-trees from the Southwest Trail that remain alive within the town, both located on what is now Main Street/Arkansas Highway 29.
In spite of a nearby skirmish, the town suffered only minor damage during the Civil War, remaining in Confederate hands until 1865. In the late 1860s and early 1870s, a major railroad line was established across Southwest Arkansas. This event was of critical importance to the history of Antoine but the new route was established about 20 miles (32 km) southeast of the former main artery of commerce (the Southwest Trail), and thereby bypassed Antoine. As a result, businesses and settlers abandoned towns along the old route, and the town began a slow decline from which it ultimately never recovered.
In the 1890s and early 20th century, there was a logging and railroad boom in the area that lasted up through the Great Depression years. During this time, railroad connections were established with Gurdon to the south, Amity to the north, and Delight to the west. The historic railroad trestle over the Antoine River was built in 1908 and remains in use today.
During the Great Depression and afterwards, Antoine experienced a slow but steady decline in population.
Today, the main activities include: logging, ranching, trucking, farming, and tourism. Most residents work in the nearby cities of: Arkadelphia, Hope, or Nashville.
