Syed Mir Abdullah Shirazi (Bengali: সৈয়দ মীর আব্দুল্লাহ শিরাজী, Persian: سید میر عبد الله شیرازی), was a Faujdar of Mughal Bengal's Sylhet Sarkar during the reign of Emperor Aurangzeb and governorship of Subahdar Azim-ush-Shan.
[2] The name Shirazi suggests that he is a Persian and originates from the Iranian city of Shiraz.
In 1699 (1110 Hijri), Abdullah built a large domed mosque in Shah Jalal's dargah complex towards the south.
[3] The ruins of this mosque can be seen, located just east of the dargah pond.
A Persian inscription was found near the ruins detailing the mosque's construction and mentions Shirazi's background.
