The purpose of this study is to assess undergraduate medical students' attitudes and practices toward volunteering activities at the Faculty of Medicine of the University of Medicine and Pharmacy in Cluj-Napoca, Romania. Methods: A cross-sectional study was conducted using anonymous questionnaires (May-June 2018) among 510 third and fifth-year students. Results: Volunteering is useful and contributes to professional development for most students. Students' interest in volunteering during or after training is influenced by many factors. Most students worked as a volunteer. Around 60.38 % of third-year students were involved in the Organization of Medical Students (OSM), only 5.38 % in some other organization, and 18.07 % in both. Among 5th-year students, 34% were involved in the Organization of Medical Students (OSM), 13% in some other organization, and 8% in both. Conclusions: The results show that most students at the Faculty of Medicine in Cluj-Napoca, Romania, recognize the value of volunteering. Undergraduate medical students are motivated and interested in this field, and for some of them, their volunteer experiences had an impact on their skills and involvement in some types of volunteerism after graduation.
