Ghiyasuddin A'zam Shah (Bengali: গিয়াসউদ্দীন আজম শাহ, Persian: غیاث‌الدین اعظم شاه) was the third Sultan of Bengal and the Ilyas Shahi dynasty.

He established diplomatic relations with the Ming Empire of China, pursued cultural contacts with leading thinkers in Persia and conquered Assam.

Bengal was interested in establishing a strategic partnership with China to counter the influence of its neighbors, including the Delhi Sultanate.

One of the earliest Muslim Bengali poet, Shah Muhammad Sagir, who was a poet-laureate of Ghiyasuddin, wrote his famous work, Yusuf-Zulekha at the request of the Sultan.
