The Battle of Kasserine Pass was a series of battles of the Tunisia Campaign of World War II that took place in February 1943 at Kasserine Pass, a 2-mile-wide (3.2 km) gap in the Grand Dorsal chain of the Atlas Mountains in west central Tunisia.

The Axis forces, led by Generalfeldmarschall Erwin Rommel, were primarily from the Afrika Korps Assault Group, the Italian Centauro Armored Division and two Panzer divisions detached from the 5th Panzer Army, while the Allied forces consisted of the U.S. II Corps (Major General Lloyd Fredendall), the British 6th Armoured Division (Major-General Charles Keightley) and other parts of the First Army (Lieutenant-General Kenneth Anderson).

The battle was the first major engagement between U.S. and Axis forces in Africa. Numerically superior but inexperienced and poorly led American troops suffered many casualties and were quickly pushed back over 50 miles (80 km) from their positions west of Faïd Pass.After the early defeat, elements of the U.S. II Corps, with British reinforcements, rallied and held the exits through mountain passes in western Tunisia, defeating the Axis offensive. As a result of the battle, the U.S. Army instituted sweeping changes of unit organization and replaced commanders and some types of equipment.
