Abdollah Khan Amir Tahmasebi (Persian: عبدالله خان امیر طهماسبی, 1881–1928) was an Iranian senior military commander, instrumental in the fall of the Qajar dynasty and rise to power of Reza Shah Pahlavi.

He first became well known in Azerbaijan for the successful restoration of law and order, gaining widespread recognition and popularity there.

He was then appointed governor of Tehran by Reza Shah, replaced in Azerbaijan by Mohammad Hosein Airom.

In 1928, while en route to Lurestan to visit a road construction site with some engineers, his group was ambushed by unknown assailants near Borujerd.

He died shortly after due to bullet wounds in a hospital in Borujerd.
