Within the neoliberal context of today’s urbanism, a growing number of inner-city megaprojects aim to transform brownfield sites—accompanied by gentrification and tourism. However, there is no systematic review exploring the interplay between these phenomena. This paper aims to systemize the existing scientific contributions by means of a literature review. Using different databases, a total number of 797 scientific documents have been identified. After several screening steps, a final set of 66 studies was included in the review. I present an analysis from a quantitative and a qualitative perspective, exploring bibliometric aspects, concepts, methods, and relevant lines of discussion. The area studied is a relatively young and emerging field. Within the discussion, there is a strong dominance of countries located in the global north, with Spain, the UK, and the U.S. at the forefront. From a methodological point of view, qualitative and mixed methods are mostly applied. The discussion of megaprojects, gentrification, and tourism has an important descriptive focus, with main topics such as planning, justice, and motivations. There are considerable conceptual deficits, as one-quarter of the studies do not clearly explain their methods. Future research needs to find ways to enable knowledge transfer to planning practice.
