Velafrons, meaning "sailed forehead," is a genus of lambeosaurine hadrosaurid dinosaur that lived during the Late Cretaceous in Mexico. Our knowledge of Velafrons comes primarily from a mostly complete skull and a partial skeleton of a juvenile specimen, featuring a bony crest on its forehead. These fossils were unearthed in the Cerro del Pueblo Formation, which dates back to the late Campanian period, approximately 72 million years ago. This discovery site was located near Rincon Colorado in Coahuila, Mexico.

In terms of its classification, Velafrons closely resembled young individuals of Corythosaurus and Hypacrosaurus, and in the scientific description of the genus conducted by Gates and colleagues, it was identified as a corythosaurin based on phylogenetic analysis. Notably, Velafrons exhibited a large skull compared to skulls of other genera at a similar developmental stage. This leads to a few possible explanations: the cranial crest in adult Velafrons may have been small or followed a distinct growth pattern. It's also plausible that adult Velafrons reached a larger size than adults of other lambeosaurine genera.

Velafrons, as a member of the hadrosaurid family, had a herbivorous diet. The available fossils include certain cervical vertebrae and a disarticulated skull. The holotype individual is estimated to have been roughly 7.6 meters in length, while fully grown adults might have reached about 10 meters in length. With this estimated adult size, Velafrons likely ranked among the larger North American hadrosaurs during the Campanian stage of the late Cretaceous.
