The present application discloses a peptide for promoting osteoanagenesis or osteogenesis, and a composition including same. The peptide or the composition including the same according to the present application has osteoanagenesis and osteogenesis functions in heterogenous bones and allogenic bones and promotes osteogenesis in a generation process too. In addition, the peptide or the composition does not exhibit heterotropic ossification. Accordingly, the composition including the peptide according to the present application can be applied to treatments of various diseases requiring osteoanagenesis and osteogenesis functions. Moreover, the peptide according to the present application can ensure safety by replacing BMP-2 or by being used with small quantities of BMP-2.
