Consigliere (pronounced [konsiʎˈʎɛːɾe]) is the Italian term for an adviser or counsellor. It is derived from the Latin consiliarius, from consilium, "advice."

Consigliere entered the popular English lexicon through Mario Puzo's Godfather novels and the subsequent films made from them. In these portrayals, the consigliere is an adviser or counselor to a mafia boss, with the additional responsibility of representing the Don in important meetings within the Don's crime family or with other crime families. The consigliere is a close, trusted friend and confidant.
