This research delves into the link between academic stress and mindfulness among undergraduate university students in Peshawar. The study involved 200 students from various universities in Peshawar (selected sample universities were University of Peshawar, CECOS University, Islamia University, National University of Modern Languages and City University), aged 18 to 25, and chosen through a multi-stage random sampling method with age and gender stratification. The Perceived Stress Scale (PSS) gauged how situations impact emotions and disrupt academics, while the Mindfulness Attention Awareness Scale (MAAS) measured mindfulness levels alongside demographic data. Statistical Package for Social Sciences (SPSS) was utilized for data analysis, encompassing descriptive and inferential stats, psychometric properties, Pearson correlation coefficient, and independent sample t-test. Findings revealed a significant negative correlation between mindfulness and academic stress, affirming both hypotheses, indicating that higher mindfulness related to lower academic stress among undergraduate university students at university level.
