Sir Muhammad Mahabat Khanji III Rasul Khanji,, was the last ruling Nawab of Junagadh of the princely state of Junagadh in India from 1911 to 1948. He was the father of Muhammad Dilawar Khanji – former Governor of Sindh and his claimed successor. Famed for his extravagant lifestyle and his love of dogs, his decision to accede Junagadh to the Dominion of Pakistan following India's Independence led to the Indian Army taking military action. He is credited with pioneering a conservation effort in what is now the Gir National Park that saved India's last few lions from almost certain extinction.

Nawab of Junagarh or Junagadh refers to the now defunct ex-lineage of rulers of the princely Junagarh State in British Raj, nowadays Junagadh district in the state of Gujarat in India. There are still several forts and palaces in India which were owned by princely Junagarh family but after Partition of India, this property was claimed by the Indian Government.
