Ahmed Niyazi Bey (1873 – 1913) (Turkish: Resneli Niyazi Bey, Ahmet Niyazi Bey; Albanian: Ahmet Njazi Bej Resnja; "Ahmet Niyazi Bey from Resen") was an Ottoman revolutionary, who was the bey of the Resne (now Resen, North Macedonia) area in the late 19th and early 20th centuries. An ethnic Albanian, Niyazi was one of the heroes of the 1908 Young Turk Revolution and of suppressing the 1909 countercoup as he played leading roles in both events. Niyazi is also known for the Saraj, a French-style estate he built in Resne.
