The increase in global tourist activities triggers the emergence of physical change phenomena known as tourism gentrification. This phenomenon is famous for its negative impact, especially on low-income people, until this process is considered a cascading hazard from disaster. Unfortunately, researchers find difficulties when trying to start research on this topic due to the absence of an overview of research trends in bibliometric studies. This research uses bibliometric analysis to analyse the effect and significance of the nations, publications, organizations, and authors that have contributed the most to this subject matter. The Scopus database was used to collect bibliographic information on pertinent studies. The selection process resulted in choosing a total of 220 articles that were published between 1990 and 2023. A bibliometric study of these publications was carried out using VOSviewer version 1.6.19 as the primary software application. Regarding tourism gentrification, the most prolific institution was located in Portugal, Universidade de Lisboa, while the most productive journal is Sustainability (Switzerland). The most prosperous nation in terms of production and cooperation was Spain. The effects of tourism gentrification, including over-tourism and touristification, have been the primary focus of research published in recent years. The link between tourism development or planning and the tourism gentrification process needs to be examined.
