Muhammad Khan Sur, also known by his regnal title Shamsuddin Muhammad Shah Ghazi, was the Sultan of Bengal from 1553 to 1555. He was initially appointed as a governor of Bengal by Emperor Islam Shah Suri of the Sur Empire in 1545, but after his death, he declared independence and re-established the Bengal Sultanate. He conquered Arakan in present-day Burma, and ordered striking of silver 'tanka' coins for Bengal.
