The Naradiya Purana or Narada Purana (Sanskrit: नारद पुराण, are two Sanskrit texts, one of which is a major Purana of Hinduism, while the other is a minor Purana (Upapurana). Both are Vaishnavism texts, and have been a cause of confusion in Purana-related scholarship. To prevent confusion, some scholars sometimes refer to the minor Purana as Brihannaradiya Purana.
Unlike most Puranas that are encyclopedic, the Brihannaradiya text is focussed almost entirely on Vishnu worship, while the Naradiya text is a compilation of 41 chapters (20%) on Vishnu worship and rest of the chapters (80%) cover a wide range of topics including a large compilation of Mahatmya (travel guides) to temples and places along river Ganges, and neighboring regions.
The Naradiya Purana is notable for dedicating eighteen chapters on other Puranas, one entire chapter summarizing each major Purana. It is also notable for its verses extolling Buddha in chapter 1.2
