The purpose of this study was to investigate students’ behavior towards knowledge sharing and the factors, individual and classroom, affecting it. Quantitative research design was used to conduct this study. Students enrolled in engineering universities, located in three provinces (Punjab, Khyber Pakhtunkhwa, Sindh) and capital (Islamabad) of Pakistan, were the population of this study. Researchers collected the data through survey questionnaires. SPSS-22 was used to analyze the collected data and for testing the hypotheses. Results revealed that the majority of engineering students’ knowledge sharing behavior was positive. Findings proved that majority of individual and classroom related factors were affecting knowledge sharing behavior of Pakistani students significantly. This is the first study which investigated Pakistani 10 engineering category universities’ students’ behavior towards knowledge sharing and factors impacting it. Results contributed in the body of literature by advancing it regarding behavior towards knowledge sharing in the context of engineering students of Pakistan. The study’s findings can play a vital role in facilitating educational institutions, students, and academicians in understanding the factors impacting students’ knowledge sharing behavior. This, in turn, might help them in removing negatively influencing factors by taking essential measures and facilitating factors with positive impact to improve students’ knowledge sharingbehavior.
