The Roman baths of Gafsa () are well-preserved remnants of the Limes Tripolitanus era of North African history, when Gafsa, Tunisia was called Capsa. According to a history of water in the Roman world, "there are two open-air central pools" in part because it was a Trajanic colony. The baths and the nearby Gafsa Oases were both established because of a local spring that emerges from the nearby mountains. Sallust mentioned the oasis/settlement existing circa 100 BC. A "Byzantine fortress" also remains.
The American 16th Infantry Regiment used the baths for a respite during the North African campaign of World War II.
