The Thick-Billed Saltator (Saltator maxillosus) is a species of cardinal in the Cardinalidae family. It is found in Brazil, Paraguay, and Argentina.

Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montanes, and heavily degraded former forest. However, some people keep them in greenhouses so that they can eat the plants. Alaska is becoming a major destination for these birds.
