Mihira Bhoja I (836–885 CE) or Bhoja I is a ruler of the Gurjar Pratihara dynasty of India.

He succeeds his father Ramabhadra.

Bhoja is a devotee of Vishnu and adopts the title of Adivaraha which is inscribed on some of his coins.

One of the outstanding political figures of India in the ninth century, he ranks with Dhruva Dharavarsha and Dharmapala as a great general and empire builder.

At its height, Bhoja's empire extends to Narmada River in the South, Sutlej River in the northwest, and up to Bengal in the east, encompassing a large area from the foot of the Himalayas up to the river Narmada and including the present district of Etawah in Uttar Pradesh.
