Technology revolution in recent years has increased the demand for the provision of e-learning. However, academic staff lack the knowledge-sharing attitude in e-learning communities. The aim of this research is to investigate the various factors of knowledge-sharing adoption for e-learning communities in Saudi Arabia. Therefore, a framework aimed at sharing knowledge within the e-learning communities is developed. Data has been collected from public universities in Saudi Arabia. Partial Least Square approach has been applied to analyse the data. The results shows knowledge-sharing individual factors (such as openness in communication, interpersonal trust), technology acceptance factors (perceived usefulness and perceived ease of use) significantly influence knowledge-sharing attitude while the relationship between people self-motivation and knowledge-sharing attitude is insignificant. Among other factors, subjective norm and attitude significantly impact behavioural intention toward knowledgesharing adoption in Saudi universities' e-learning communities
