Chushan-Rishathaim (כּוּשַׁן רִשְׁעָתַיִם) was king of Aram Naharaim or Northwest Mesopotamia. In the book of Judges God delivers the Israelites into his hand for eight years (Judges 3:8). However, they are delivered from him by Othniel, son of Kenaz (Judges 3:9).
Rishathaim means double-wickedness[1].
