The research method used is a quantitative approach with an ex post facto design. The research population consists of all 120 active students, with a sample of 32 students selected using random sampling technique. The research instrument is a Likert scale questionnaire to measure the intensity of tarekat practice and the character indicators of the students. Data were analyzed using simple linear regression. The results of this study indicate that there is a significant influence of the application of the Naqshbandi Order on the character formation of students. Thus, the higher the intensity of practicing the Order, the better the character that is formed. The application of the Naqshbandi Order significantly affects the formation of students' religious character, discipline, responsibility, simplicity, and independence. Religious studies, the practice of dhikr, suluk, and guidance from the mursyid are the main factors that encourage the formation of noble character among the students.
