Little is known about the location of Uz.  We are told that Job is from the land of Uz, but we are not certain where that actually is.  There is some evidence to suggest that Job lives in Syria, but other evidence suggests that Uz is in Jordan or even southern Israel.  The best indication we are given as to its location is that there is an attack by Chaldean raiders, Chaldea being where modern day Iraq is located.  This might give reason to believe that Uz is near or borders the area of Iraq but no one is certain.
