Hamun-e Jaz Murian (Persian: هامون جازموریان) is an inland basin or depression in southeast Iran, straddling the provinces of Kerman and Sistan-Baluchistan.

The Jazmurian Wetland is located in an endorheic basin at the southern edge of the Dasht-e-Lut.

Jaz Murian is an oblong shape, east to west, surrounded by high mountain ranges reaching peaks in excess of 6500 feet (2000 m).

The lowest elevations are to the extreme west of the basin towards the towns of Kahnuj and Minab.

In the scriptures of the Zoroastrian religion, the basin has a holy character, similar to that of Hamun-e Helmand.
