Kamnaskires III (also spelled Kammashkiri III) was the Kamnaskirid king of Elymais from 82/1 BC to 75 BC. Elymais had since 124 BC been under complete Parthian control. However, in 81/80 BC, coins of king Kamnaskires III and his wife Anzaze appears, which indicates that the kingdom had been restored. According to Babylonian sources, the incumbent Parthian monarch Orodes I launched an expedition into Elymais in 78 BC, where he defeated Kamnaskires III. Kamnaskires III was not deposed, however, and continued ruling the kingdom now as a Parthian vassal. Kamnaskires III's successor is unknown, however, it is known that Kamnaskires IV ruled Elymais from 62/1 BCE.
