This study performed literature analysis to understand the definitions and implications of visionary leadership. Based on the analysis, the following results were obtained: (1) visionary leadership is an educational leadership theory emphasizing that the principal establishes goals collectively with teachers and leads teachers to realize the goals; (2) the implementation strategies of visionary leadership involved committing to the vision, fulfilling the vision, making good use of resources, team learning, stimulating actions, and adopting accreditation mechanisms; and (3) most of the domestic studies have focused on junior high and elementary schools; therefore, a lack of visionary leadership outcomes in other educational stages were observed. According to the aforementioned results, this study proposed three recommendations: (1) the education authorities should provide training courses related to visionary leadership for school principals; (2) scholars can continue to explore visionary leadership; and (3) localized content of visionary leadership should be developed. This study can serve as a reference for future studies.
