Since both communication within the organization and leadership are two key elements in attaining organizational goals, they are key determinants and are of vital importance in terms of the organization's current achievement and efficiency, and its future position. The present study, which inquires the relationship between intra-organizational communication and leadership through an interactive approach, evaluates the existing interaction from the perspective of both the leader and intra-organizational communication, and attempts to reveal the direction, form and level of the influence of intra-organizational communication and the leader on each other. In this sense, while the leader at the head of the organization is in a position to influence the communication system of the organization positively or negatively through the decisions taken, his behaviors will also be exhibited. Likewise, the communication system of the organization is in a determinative position in evaluations about the leader and his leadership in his success or failure. Therefore, it is emphasized that the leader should pay due attention to intra-organizational communication.
