Proposal and Originality Our main objective is to conduct a systematic literature review (SLR) to characterize the current state of digital twinning (DT) technology implemented in tourism-related applications. We aim to understand the current development of DT applications in tourism, evaluate the types of DT implemented or described, the main components used in these DT, their purposes, and the types of tourism where the technology is used. To the best of our knowledge, no SLR on the usage of DT technology on tourism was conducted so far. Methodology We conducted the SLR with bibliometric analysis using the methodology proposed by Carrera-Riviera et al.(2022). A total of 28 peer-reviewed studies from 3 major scientific databases were selected for review. A taxonomy of 7 criteria or dimensions was used to classify the studies: tourism type, purpose, spatial scale, data sources, data linkage, visualization, and application. Results and Implications The topic is at an early stage, as the oldest study found dates back to 2021, but its research is increasing every year. Most reviewed studies deal with cultural tourism, focusing on the digitization of cultural heritage. The data linkage between real and digital counterparts is mainly unilateral, so the real entity cannot synchronize with the DT. The number of theoretical and applied studies is similar, suggesting progress in the application of the technology in the field. Finally, we conclude that there is a large research gap regarding DT technology in tourism, which is worth filling. Research Limitations Using only three search engines may compromise validity, as others could have provided more results. More variations of the search strings could yield more relevant articles.
