This study was aimed to investigate the current situations of coaches' leadership behavior perceived by university basketball players and team cohesion and their correlation. The male and female basketball players of the A2 Basketball Games in School Year 100, 350 people in total, were regarded as the research objects. The average age was 20.19±2.32 years old. The approach of questionnaire survey was applied to the data collection and analysis. In total, 350 copies of questionnaire were delivered, and 342 valid copies were retrieved, namely the valid response rate was 97.7%. To analyze the data, a descriptive analysis was first employed to understand the current overview of the university basketball players. Pearson's correlation coefficient was then used to investigate the linear correlation between the coaches' leadership behavior perceived by the basketball players and the team cohesion, the correlation significance of each item was determined, and the results were explored. According to the results, there were more male players than female players. Most of the players were trained for 3~6 years. They practiced for 3~4 days every week. The evaluations of most of the players were of high trust in terms of four dimensions in coaches' leadership behavior perceived by players, respectively training and instruction behavior, democratic behavior, appreciation behavior, and caring behavior. Furthermore, most of the players tended to hold a sense of identity in terms of four dimensions in team cohesion, namely teamwork, interpersonal affinity, team adaption, and interpersonal attraction. In the correlation analysis of coaches’ leadership behavior perceived by players and team cohesion, the dimensions of both coaches' leadership behavior perceived by players and team cohesion were positively correlated, indicating that the overall team cohesion of a team will increase when coaches' leadership behavior increases. In particular, the dimension of ”training and instruction behavior” in coaches' leadership behavior perceived by players was the most significantly correlated to the dimension of ”teamwork” in team cohesion.
