绰罗斯（蒙古语：ᠴᠣᠷᠣᠰ，西里尔字母：Чорос）是蒙古族准噶尔部和杜尔伯特部的一个姓氏或氏族，乃准噶尔部的王族，并一度统治整个卫拉特四部。

15世纪上半叶的瓦剌首领马哈木、脱懽、也先都属于绰罗斯部。也先死后，绰罗斯逐渐式微。

17世纪，绰罗斯首领哈剌忽剌、噶尔丹在第五世达赖喇嘛·罗桑嘉措的支持下再次称霸西蒙古，创建准噶尔汗国。

Choros or Tsoros (Mongolian:Цорос) was the ruling clan of the Dzungars and Dörbet Oirat and once ruled the whole Four Oirat. They founded the Dzungar Khanate in the 17th century. Their chiefs reckoned their descent from a boy nourished by a sacred tree.
