Salman Pak (Arabic: سلمان باك ‎) is a city approximately 15 miles south of Baghdad near a peninsula formed by a broad eastward bend of the Tigris River. It is named after Salman the Persian, a companion of Muhammad who is buried there.

It is quite close to the Salman Pak facility, an Iraqi military installation which was a key center of Saddam Hussein's biological and chemical weapons programs. It is also alleged to have been the site of a training facility used by Iraqi intelligence to train militia groups.

Salman Pak is also site of the Arch of Ctesiphon, one of the largest and oldest freestanding arches in the world.
