Tell Bazmusian (also Tell Basmusian) is an archaeological site on the right bank of the Little Zab in the Ranya Plain (Sulaymaniyah Governorate, Iraq).

The site was excavated between 1956 and 1958, with the first season directed by Abu al-Soof and the remaining two seasons by A. al-Tikriti, as part of a salvage operation to document cultural remains that would be flooded by Lake Dukan, the reservoir created by the Dukan Dam which was being built at that time.

[2] The excavations have revealed 16 occupation layers, ranging from the Samarra culture (sixth millennium BCE) up to the ninth century CE.

Level III, to be dated to the late second millennium BCE, contained a single-room temple with thick mudbrick walls.

Levels VI–XVI contained material dating to the third millennium BCE, the Uruk period and of the Samarra and Halaf cultures but this has not yet been published.
