The Catepanate of Ras was a province (catepanate) of the Byzantine Empire, established around 971 in central regions of early medieval Serbia, during the rule of Byzantine Emperor John Tzimiskes (969–976). The catepanate was named after the fortified town of Ras, eponymous for the historical region of Raška. The province was short-lived, and collapsed soon after 976, following the Byzantine retreat from the region after the restoration of the Bulgarian Empire.

Ras, known in modern Serbian historiography as Stari Ras, is a medieval fortress and area located in the vicinity of former market-place of Staro Trgovište, some 10–11 kilometers (6.2–6.8 mi) west of modern-day city of Novi Pazar in Serbia.
