Tylocephale (meaning "swollen head", from the Greek τυλη meaning 'callus' or 'hard swelling' and κεφαλη meaning 'head') is a genus of pachycephalosaurid dinosaur from the Late Cretaceous Period. It was a herbivorous dinosaur estimated to have been about 1.4 metres (4.6 ft) in length. It had the tallest dome of any known pachycephalosaur.

Tylocephale lived during the Campanian stage, around 75 million years ago. It was discovered in the Khulsan region of Mongolia. The type species is T. gilmorei, described by Maryańska and Osmólska in 1974.
