Liu et al., (2019) stipulated that both critical thinking and caring behaviours are the crucial elements in professional nursing education. Some studies shown that both nurses and nursing students were struggling with their critical thinking skills (Akca & Selen, 2015) and (Lee et al., 2020). This indicated that the quality of care and the effectiveness of the services will be affected by the lack of critical thinking skills (Arli et al., 2017), and caring behaviours. Objective: To assess the level of critical thinking among UNIMAS undergraduate nursing students, to identify the perceived caring behaviours among UNIMAS undergraduate nursing students and to examine the relationships between critical thinking and caring behaviours among UNIMAS undergraduate nursing students. Method: Cross sectional research design with a quantitative approach was utilised in which a total of 133 of UNIMAS undergraduate nursing students were selected using the simple random sampling. Result: The findings of this study showed that the UNIMAS undergraduate nursing students possessed a moderate critical thinking and caring behaviours with the total mean scores of 69.54 (SD=7.749) and 121.46 (SD=18.804) respectively. There was a weak and statistically significant positive correlation between the critical thinking and caring behaviours (r=0.331, n=133, p<0.001). Conclusion: This study could act as a medium in generating the awareness regarding the importance of the critical thinking and caring behaviours and the consequences of lacking in both variables
