This study aimed to determine nursing students' views on sustainability and their awareness levels in this regard. The study has a mixed research design. No sampling was made, and it was aimed to access the whole population. Two hundred twenty-two students were included in the quantitative part of the research, while 16 students participated in the qualitative part. In the study, the Sustainability Awareness Scale and a semi-structured interview form were used. The quantitative and qualitative data were analysed both separately and in combination. The mean age of the participants was 20.85 ± 1.638 years, and the total scale mean score was 42.80 (38.800-47.200). Family type affects sustainability awareness. The participants reported 103 opinions on sustainability. These opinions were grouped under 4 main themes and 18 subthemes. Two subthemes obtained from the qualitative data were evaluated as "complementary", and two subthemes were considered "convergent". Nursing students had a low level of sustainability awareness. To nursing students, sustainability means environmental awareness, justice, renewability, and continuity. Nursing is a profession that is effective in ensuring sustainability. Incorporating sustainability into nursing education will contribute to sustainability in society, especially the sustainability of community health.
