Opal-crowned Tanager occurs in western Amazonia, in the countries of Colombia, Brazil, Peru, and Ecuador (Isler and Isler 1987), more specifically, from southeastern Colombia south through eastern Ecuador and southeastern Peru, and in adjacent western Brazil (Isler and Isler 1987). Opal-crowned Tanager occurs mostly below 600 m in eastern Ecuador (Ridgely and Greenfield 2001), and in Bolivia, Naoki (2003) found it only from 100-400 m. In southern Peru, however, it may occur up to 950 m (Parker et al. 1996, Walker et al. 2006). The center of elevational abundance is in the lower tropical zone (Parker et al. 1996). This species occurs in the Zoogeographic Regions of Northern Amazonia and Southern Amazonia (Parker et al. 1996).
