This study examines the development of Islamic Financial Literacy (IFL) as an increasingly important topic within the field of Islamic economics and finance. Despite the growing number of publications, existing studies remain fragmented in terms of conceptualization, determinants, and outcomes, creating the need for a more comprehensive synthesis. Therefore, this research aims to systematically review and map the literature on IFL, identify its main themes, determinants, and outcomes, and highlight existing research gaps as well as future research directions. To achieve these objectives, the study employs a hybrid approach by integrating a systematic literature review (SLR) using the PRISMA framework with bibliometric analysis based on Scopus-indexed publications. VOSviewer is utilized to visualize keyword co-occurrence, research clusters, and publication trends. The findings reveal that IFL is a multidimensional construct influenced by religiosity, socio-demographic factors, and psychological variables such as self-efficacy and self-concept, and is strongly associated with positive financial behavior and well-being. The analysis also shows that the field is well-established yet continues to expand globally, including in non-Muslim-majority countries. However, significant gaps remain, particularly in the lack of standardized measurement, methodological diversity, and integration with emerging issues such as financial technology. In conclusion, this study provides a structured and comprehensive understanding of IFL and offers a foundation for future research to enhance its theoretical and practical contributions.
