Mandhata (Hindi: मान्धाता), also called Shivapuri or Omkareshwar, is an island in the Narmada river in Khandwa district, Madhya Pradesh, India. Omkareshwar Jyotirlinga is situated on the southern part of the island. Omkareshwar Mandhata is located on the Mandhata hill on the banks of the Narmada.
The name "Omkareshwar" is due to the shape of the island, which appears to be Om. It is about 2 km long and 1 km wide. Local tradition reveals that King Mandhata paid homage to Shiva here and made this holy place his capital.
