Gettyia is an extinct genus of avisaurid enantiornithean bird from the Late Cretaceous of North America.
== Description == Gettyia is known from a single right tarsometatarsus. This bone was similar to that of other North American avisaurids such as Avisaurus and Mirarce, but it was much smaller. The second metatarsal had a tubercule (knob-like structure) on its front edge, which likely connected to the tibialis cranialis muscle which flexes the ankle. Other avisaurids typically had this tubercule located midway on the shaft of the metatarsal, or closer to the ankle than the toes. Gettyia, on the other hand, had its tibialis cranialis tubercule located more than halfway down the shaft. The third and fourth metatarsals are more extensively fused than in other avisaurids, as fusion occurs not only near the ankle, but also near the toes.
