Udayagiri and Khandagiri caves, formerly called Kattaka Gumpha or Cuttack caves, are partly natural and partly artificial caves of archaeological, historical and religious importance 3 km south of the city of Bhubaneswar in Odisha, India. The caves are situated on two adjacent hills, Udayagiri and Khandagiri mentioned as Kumari Parvata in the Hathigumpha inscription. They have a number of finely and ornately carved caves built during the 1st century BCE.
