Leadership has been at the center of social and organizational life throughout history and has been shaped under various approaches in different periods. Among these approaches, visionary leadership has become a prominent theoretical and practical leadership approach, especially since the last quarter of the 20th century. Visionary leadership involves not only creating a strong and inspiring vision of the future but also sharing this vision with organizational members and motivating them towards a common goal. In this respect, it is considered a strategic necessity for contemporary organizations to survive in an environment of change, uncertainty, and competition. This study examines the concept of visionary leadership through a literature review and discusses its basic components, its relationship with other types of leadership, and its functions in today's organizational context. The review of the literature reveals that visionary leadership guides organizations in strategic, psychological, cultural, and communicative dimensions and is closely related to factors such as corporate culture, innovation, and employee engagement. In addition, visionary leadership provides long-term competitive advantage to organizations in relation to current issues such as digitalization, sustainability, and crisis management. The study considers visionary leadership as an organizational reflex and a cultural construct rather than an individual quality and emphasizes that the concept should be understood not only as leader-centered but also as a shared and institutionalized vision. This approach provides a theoretical framework for the literature and a holistic view of the stages of vision development, sharing, realization, and maintenance for practitioners.
