Background: Authentic leadership can fulfill secondary requirements of nurses as well as foster a transparent and fair environment, which has a direct impact on their work performance, creativity, progression, and ethical behaviors. Aim: This study explored the staff nurses' perspective on authentic leadership's role in creativity, job crafting, and deviant behaviors at work. Subjects and methods: Design: A descriptive-correlational design was used. Setting: King Khalid Hospital and Prince Sattam University Hospital. Subjects: A convenience sample of 325 staff nurses was recruited. Tools: Including four tools: the authentic nurse leader questionnaire-staff leader evaluation, creativity scale of nurses, job crafting questionnaire, and workplace deviance scale. Results: The result suggests that nurses had a moderate perception of authentic leadership (56.77±14.35), moderate creativity (47.90±10.42), high job crafting (69.36±11.99), and a low level of deviant behaviors (27.66±7.94). In addition, the results revealed a highly significant positive correlation between authentic leadership and creativity and a significant positive correlation between creativity and job crafting. Conversely, a negative relationship existed between deviant behavior and genuine leadership, creativity, and job crafting. Conclusion: Authentic leadership is vital in enhancing nurses' creativity and may also reduce deviant behavior. Recommendation: Leaders and supervisors should be trained in the skills necessary for authenticity, which fosters the innovative, productive, and ethical conduct of nurses. Further  investigations are recommended in this area.
