Leaders' self-realization and their intra-group behaviors at work are influenced by elements such as a sense of meaningful purpose and intrinsic motivation. This study aims to construct a model of meaningful leadership, based on the values, aspirations, and attitudes of a leader and how these qualities help them develop positive organizational cultures. The research, based on constructivist grounded theory design, utilized semi-structured interview technique with 15 teachers, examining their perceptions of meaningfulness and leadership. These interviews revealed ten core dimensions of meaningful leadership: An ultimate purpose in life, sharing meaning, understanding, linking the past, present, and future, wisdom, peacefulness, a sense of ethics, serving others, inner motivation, and fostering unity. These dimensions can be considered essential when identifying meaningful leaders. This proposed model of leadership, with a focus on meaningfulness, can play a pivotal role in an organization by contributing to self-realization of members and ensuring the unity of purpose. In educational organizations, a meaningful leadership approach can leverage leaders' efforts by providing an intrinsic motivation source for all school members.
