Khirbet el-Fityan is the remains of a small Roman military fort located about 1.5 km southwest of the great Roman legionary fortress of El-Lejjun (ancient Betthorus) in central Jordan. Built to support the frontier defences of the province of Arabia, the fort formed part of the Roman military network that protected the strategic route known as the Via Nova Traiana and monitored movement across the surrounding plateau.

Although much smaller than the imposing fortress at El-Lejjun, Khirbet el-Fityan played an important supporting role. It was likely occupied by a small detachment of soldiers responsible for patrolling the surrounding countryside, maintaining communications with Betthorus, and providing an early warning against threats approaching from the desert.

Today, visitors can still distinguish the rectangular outline of the fort, with sections of its stone walls preserved around the perimeter. The ruins include the remains of defensive walls, corner towers, internal rooms, and traces of the central courtyard, all constructed from locally quarried limestone. While much of the structure has collapsed over the centuries, its original plan is recognisable.
