Privacy in the information systems (IS) context is becoming increasingly challenging and complicated. This study conducted a systematic review of the information privacy literature in the IS context to identify theories to understand and explain online information privacy. We reviewed eight journals from the Association for Information Systems over the 10-year period from 2013 to 2023. These journals were identified as mainstream in the IS discipline by senior scholars in the field. We identified and explored 20 theories in depth. Our findings have important implications for academics and practitioners. Scholars can build on our findings to identify and adopt promising theories from other disciplines to be contextualized and applied to examining information privacy. New theories can enrich our understanding of information privacy and provide in-depth insights from different perspectives, thereby enhancing our understanding of information privacy issues.
