Grabos (or Grabus; {{langx|grc|Γράβος}}; ruled c. 437–423 BC) was an Illyrian chieftain who is mentioned once in an Athenian inscription in 423 BC. He or his son (possibly Sirras) were the leaders of the Illyrians who supported the Lyncestians against an expedition by the Macedonians in 423 BC.{{sfn|Heckel|2016|p=20}} The Illyrian-Lyncestian troops defeated the Macedonian-Spartan alliance.

He probably was the grandfather of Grabos II.{{cite book|last=Cabanes|first=Pierre|title=Iliri od Bardileja do Gencia (IV. – II. stoljeće prije Krista)|trans-title=The Illyrians from Bardylis to Gentius (4th – 2nd century BC)|year=2002|orig-year=1988|language=hr|translator=Vesna Lisičić|publisher=Svitava|editor1=Dinko Čutura|editor2=Bruna Kuntić-Makvić|isbn=953-98832-0-2|page=51}}{{cite journal|last=Šašel Kos|first=Marjeta|title=Pyrrhus and Illyrian Kingdom(s?)|journal=Greek Influence Along the East Adriatic Coast|series=Knjiga Mediterana|volume=26|year=2002|isbn=9531631549|url=https://books.google.com/books?id=QeKAAAAAMAAJ|page=113}}James Augustus St. John, The History of the Manners and Customs of Ancient Greece, 1842 Volume 3, page 275 (reprint 2003, ISBN 1-4021-5441-0)D.
