Leptorhynchos is an extinct genus of caenagnathid that lived in North America during the Late Cretaceous.
Description[]
Leptorhynchos is distinguished by two autapomorphies: Its smaller size than Chirostenotes and Anzu and a slightly upturned mandible. This means that Leptorhynchos was likely herbivorous. Leptorhynchos elegans has been transferred to Citipes.
