Coelurosauria (; from Greek, meaning "hollow tailed lizards") is the clade containing all theropod dinosaurs more closely related to birds than to carnosaurs. Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only dinosaur group alive today. Most feathered dinosaurs discovered so far have been coelurosaurs; Philip J. Currie considers it probable that all coelurosaurs were feathered. In the past, Coelurosauria was used to refer to all small theropods, although this classification has been abolished.
