Corwin Sullivan is a Canadian vertebrate palaeontologist known for his research into the evolution of archosaurs.
Sullivan completed his undergraduate degree at the University of Victoria, going on to earn a master's degree from the University of Toronto at Mississauga and a doctorate from Harvard University. After spending time as a faculty member at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), he became the inaugural holder of the Philip J. Currie Professorship in Vertebrate Paleontology at the University of Alberta, named after Philip J. Currie. He also serves as the curator of the Philip J. Currie Dinosaur Museum in Grande Prairie, Alberta.
Sullivan has extensively studied the functional morphology of theropod dinosaur<nowiki/>s, especially those phylogenetically close to birds, in an effort to gain insight as to how wings evolved in the theropod lineage.
