Pushpagiri (Odia: ପୁଷ୍ପଗିରି) was an ancient Buddhist mahavihara or monastic complex located atop Langudi Hill (or Hills) in Jajpur district of Odisha, India. Pushpagiri was mentioned in the writings of the Chinese traveller Xuanzang () and some other ancient sources. Until the 1990s, it was hypothesised to be one or all of the Lalitgiri-Ratnagiri-Udayagiri group of monastic sites, also located in Jajpur district. These sites contain ruins of many buildings, stupas of various sizes, sculptures (many now removed to museums), and other artifacts.
