Kanva (Karnesh) (Sanskrit: कण्व káṇva) was an ancient Hindu rishi of the Treta yuga, to whom some of the hymns of the Rig Veda are ascribed. He was one of the Angirasas. He has been called a son of Ghora, but this liniage belongs to Pragatha Kanva, a subsequent Kanva of which there were many. However, Puranic literature has other different lineages for him, one as the son of Apratiratha and grandson of King Matinara, and another as the son of Ajamidha, who was a descendant in the ninth generation of Tansu, the brother of Apratiratha (Atiratha), or Ajamidha who was a contemporary of Matinara. This last seems to be the modern consensus. He is sometimes included in the list of the seven sages (the Saptarishis). Kanva had a son Medhatithi.
