In tourism research, memorable tourism experience represents a popular perspective for evaluating tourism experiences. Kim, Ritchie, and McCormick (2012) developed a related scale applicable across various tourism contexts, though some controversies remain. This paper employs systematic literature review and bibliometric analysis methods to deeply explore international research progress on MTE, including its definition, differentiation, context, measurement, dimensions, antecedents, and consequences, and constructs a comprehensive research framework based on these findings. Key findings: (1) Memorable tourism experience can be defined as a post-travel experience sufficiently significant to be retained in long-term memory, with substantial influence on tourists’future behavioral decisions. (2) Research development can be divided into four stages: “germination period”, “formation period”, “development period”and“critical development period”. (3) MTE measurement currently relies on four main methods, for which this study provides in-depth analysis of applicable conditions. Regarding the seven-dimensional scale developed by Kim, Ritchie, and McCormick (2012) and its application in empirical studies, this paper finds that hedonism, involvement, novelty, and meaningfulness are the most prevalent dimensions for predicting tourist behavior. It also identifies potential new dimensions, including social interaction, perceived serendipity, negative feelings, and pleasure. (4) Based on CiteSpace literature clustering analysis, five major research themes are identified:“MTE frontiers”, “MTE modeling”, “cultural heritage tourism and experience co-creation”, “destination attributes and experience management” and “MTE and well-being”. Focusing on empirical research, the study systematically summarizes the driving factors, effects, and mechanisms of MTE. (5) For future research, six directions are proposed: conducting specific memory structure research across diverse populations, strengthening focus on negative MTE; promoting application of memory characteristic scales; expanding studies on MTE effects; constructing theoretical frameworks for memory management; promoting the integrated development of service-dominant logic.
