The Prairie Grove Battlefield State Park is a state park located in Prairie Grove, Arkansas. It memorializes the Battle of Prairie Grove, fought on December 7, 1862, during the American Civil War. The battle secured U.S. Army control of northwestern Arkansas.

The Battle of Prairie Grove was a battle of the American Civil War fought on December 7, 1862. While tactically indecisive, the battle secured the Union control of northwestern Arkansas. A division of Union troops in the Army of the Frontier, commanded by James G. Blunt, was posted in northwestern Arkansas after winning the Battle of Cane Hill on November 28. The 1st Corps, Trans-Mississippi Army, commanded by Thomas C. Hindman moved towards Blunt's division in order to attack while it was isolated. However, Blunt was reinforced by two divisions commanded by Francis J. Herron, leading Hindman to take a defensive position on some high ground known as Prairie Grove. Herron attempted to assault Hindman's lines twice, but both attacks were beaten off with heavy casualties. Hindman responded to the repulse of each of Herron's attacks with unsuccessful counterattacks of his own. Later in the day, Blunt arrived and attacked Hindman's flank. Eventually, both sides disengaged and the fighting reached an inconclusive result. However, the unavailability of reinforcements forced Hindman's army to retreat from the field, giving the Union army a strategic victory and control of northwestern Arkansas. Union forces reported suffering 1,251 casualties (including 175 dead); Confederate forces reported 1,317 casualties (between 164 and 204 dead). Confederate forces suffered from severe demoralization, and many conscripts deserted. The Confederates had to leave many of their dead on the field, in piles and surrounded with makeshift barriers to keep feral pigs from eating the corpses. Today, a portion of the battlefield is preserved within Prairie Grove Battlefield State Park.
