Fort Lookout, also known as Redoubt A, is a defensive earthworks erected during the American Civil War on the outskirts of Camden, Arkansas.

Immediately west of the main works is an L-shaped redoubt which commands potential fording sites at the base of the bluff.

From January to March Confederate troops and slave labor worked to develop a series of five redoubts, mainly to protect the southern and western land-based approaches to the city.

Union Major General Frederick Steele, in command of the forces occupying Little Rock, was ordered to move southwest to effect a junction with Major General Nathaniel Prentice Banks' Red River Campaign, a push to take Shreveport, Louisiana and eventually gain a Union foothold in Texas.

Needing provisions, Steele ordered his forces to march on Camden, which they occupied on April 15 after it was abandoned by its small number of defenders.
