The objective of this research was to identify the set of municipalities that are configured as tour‑ ist areas in the State of Paraná, Brazil, considering the concentration and specialisation of their tourist at‑ tractions. In order to achieve this goal, mathematical tools were applied as a means to define the degree of concentration, measured by the Herfindahl‑Hirschman Index (HHI), and the level of specialisation, calculated using a Location Quotient (LQ), of the tourism in the municipalities. The origin of the data analysed came from TripAdvisor and from the Secretary for Employment at the Ministry of Economy. The importance of this study is the need for instruments that subsidize the decision‑makers from public and private sectors in the elabora‑ tion of strategic planning for municipalities or regions. The results obtained point to the conformation of tourist spaces around the large demographic centers, highlighted the municipalities of Foz do Iguaçu, Curitiba and Paranaguá, by specialization and concentration criteria of tourism in the State. Furthermore, it was possible to identify isolated tourism destinations, which have very specific and unique attractions, as Iretama, Verê, Mal‑ let and Tijucas do Sul, besides the growth potential of other tourism areas like Ponta Grossa, Prudentópolis, Cascavel e Guarapuava
