Sarlagab or Zarlagab was a Gutian ruler mentioned on the Sumerian king list as reigning for 6 years, possibly ca. 2129 BC to 2126 BC.
Sarlagab may have been a contemporary of the Akkadian king Shar-kali-sharri, if he is the same Gutian king Sharlag whom Shar-kali-sharri captured according to one of his year-names.
