Adherence to professional ethics based on spiritual intelligence is conducive to patient welfare and satisfaction. The purpose of this study was to determine the relationship between professional ethics and spiritual intelligence of Kerman University of Medical Sciences' students. In this descriptive co relational study, 150 undergraduate medical students were enrolled in the census. The tools used were spiritual intelligence and professional ethics questionnaires. Data were analyzed by SPSS version 22 using independent t-test, one-way ANOVA, and Pearson correlation coefficient. The mean and standard deviation of professional ethics score was 57.72±6.2 and the spiritual intelligence of students was 73.97±12 12.3. The lowest score of professional ethics was in the area of responsibility and the most in sympathy with others. There was also a significant positive relationship between professional ethics scores and students' spiritual intelligence (P = 0.001). This means that by educating and enhancing students 'spiritual intelligence during their studies, one can expect to increase students' professional ethics during clinical work and professional communication with the patient. To this end, teachers' emphasis on aspects of ethical applied education, especially during clinical education, as well as honoring spiritual patterns as the foundation of ethical education during college education seems necessary.
