Elburz (also Alborz or Alburz) is a mountain range in northern Iran, stretching from the border of Azerbaijan in the north-west around the southern end of the Caspian Sea (where also Teheran and Iran's highest peak, Damavand (5604m) are), and ending in the east at the borders of Turkmenistan and Afghanistan.

Not to be confused with the Elbrus mountain in the Caucasus mountains.
