Leadership is a concept since the being of humankind. But there is no consensus about its definition and measurement. As a result of this situation, a number of leadership styles have been defined. For instance, transformational, transactional and charismatic leadership approaches have been discussed frequently these days. But, it is not clear what the overall trend on transformational leadership in health sector and also in Turkey. For that, it is aimed to examine the national and international studies carried out on transformational leadership in the health sector. Ebscohost, Google Scholar, Sciencedirect, Scopus, TÜBİTAK ULAKBİM and YÖK National Thesis Center were scanned to achieve the objectives of the study and 66 studies, 57 in Turkish and 9 in English were examined. It was determined that the first studies on transformational leadership in the health sector were carried out in 2006. Also, most of the studies were carried out in the last 5 years. It is also seen that some concepts such as leadership, organizational commitment, and employee performance are frequently studied. It is considered that this research is really important in terms of revealing the overall trend of transformational leadership in the health sector and identifying research subjects that had not been studied.
