The Qarinvand dynasty (also spelled Karenvand and Qarenvand), or simply the Karenids, was an Iranian dynasty that ruled in parts of Tabaristan (Mazandaran) in what is now northern Iran from the 550s until the 11th-century. They considered themselves as the inheritors of the Dabuyid dynasty, and were known by their titles of Gilgilan and Ispahbadh. They were descended from Sukhra, a Parthian nobleman from the House of Karen, who was the de facto ruler of the Sasanian Empire from 484 to 493.
