In Greek mythology, Clonius (Ancient Greek Κλονίος) is one of the five Boeotian captains in Homer's Catalogue of Ships. Parentage varies — Alegenor; Alector and Acteis; or Lacritus and Cleobule (then brother of Leitus). He falls to Agenor, Antenor's son, in the fighting before Troy.

I.Boeotian captain at Troy
Homer (Iliad 2.494–510) lists Clonius among the leaders of the Boeotian fifty ships. Hyginus (Fabulae 97, 114) makes him son of Lacritus and Cleobule and brother of Leitus; other authorities give Alegenor or Alector and Acteis. In Iliad 15 he is killed by Agenor.
Wikipedia's Clonius page also lists an illegitimate son of Priam, two Aeneid companions, and a Theban defender against the Seven — none of which is this Boeotian captain.
II.Homonym care
The atlas id clonius is the Homeric Boeotian leader alone. Cleobule his Hyginian mother is cleobule-boeotian, distinct from other Cleobules.
