Siyâvash (), also spelled Siyâvoš or Siavash (), is a major figure in the Shahnameh. He is introduced by Ferdowsi as the son of Kay Kāvus, who reigns as Shah in the earliest days of Greater Iran for over a century. His name means "the one with black stallions" after his horse Shabrang Behzād (, ), who accompanies him during a trial of righteousness.
