Increasingly, the literature highlights the importance of implementing and developing socially responsible behaviours by all stakeholders in the tourism sector. This paper describes the evolution of research on social responsibility in the tourism sector until July 2020. We compiled a database of 846 articles focused on the field and published in academic journals in the ISI WoS database. Bibliometric methods and techniques were used to describe the evolution of scientific activity, countries and active institutions, most productive authors, most relevant sources, most influential documents, trend topics, and social structure researched. This determined the state of the art and described the evolution of the literature in this field, and will help scholars refine existing and initiate new research agendas. A total of 846 papers were identified and the results showed an upward trend in scientific production relating corporate social responsibility (CSR) to tourism. Based on these analyses, possible forms of future research are proposed to advance towards the consolidation of this scientific discipline.
