Dharmrajeshwar, Archaeological site in Mandsaur district, India.

Dharmrajeshwar is a cave temple carved directly from solid rock, featuring a main sanctum with intricate sculptures and multiple smaller shrines built into the stone. The structure includes several chambers connected by passages, with carved architectural details throughout the complex.

The rock-cut temple complex dates to the 8th century. It was first a shrine dedicated to Vishnu and was later remodelled as a Shiva temple, so the sanctum sanctorum holds both an icon of Harihara and a Shivalinga. The site lies about 100 km from Mandsaur, and the Hindi source places its construction in the 4th–5th century.

The sanctum holds both an icon of Harihara, a combined form of Vishnu and Shiva, and a Shivalinga, reflecting the site's shift from a Vishnu shrine to a Shiva temple. Mahashivaratri is the main festival celebrated here. A plaque on a low stone block near the entrance carries an inscription, though its text is not legible in photographs.

The site lies about 100 km from Mandsaur; the nearest railway station is Shamgarh. The shrine is cut into a rock face, entered through a modern metal-framed glass door set in the central rectangular opening, with seated and standing figures carved in recesses on either side. A low stone block in the left foreground carries a plaque.

The sanctum holds both a Harihara icon and a Shivalinga, a pairing left from the site's change of use: it was founded as a Vishnu shrine in the 8th century and later remodelled for Shiva. Mahashivaratri is the main festival held here.
