Rukn ad-Dīn ʿAlī Mardān Khaljī (Bengali: রোকনউদ্দীন আলী মর্দান খলজী, Persian: ركن الدین علی مردان خلجی) was a 13th-century governor of Bengal, a member of the Khalji dynasty of Bengal.

He was a son of Mardan Khalji of the Khalaj tribe,[1][2][3][4] a tribe of Turkic origin that after migration from Turkistan had later settled in Afghanistan for over 200 years before entering South Asia.

However, he only ruled for two years as his cruelty and brutality produced disgust among the courtiers.

Some of his actions included banishing popular nobles from Bengal who he did not get along with.
