It is estimated that by 2050, 90 percent of the population of Latin America will be living in urban areas (UN DESA, 2018), as this poses a challenge to cities, which need to seek solutions to improve the quality of life of their inhabitants and still be capable of attracting investments and visitors, developing strategies that make them stand out worldwide. Aiming to improve the quality of life, the efficiency of services and the competitiveness of urban centers, through technology, respecting economic, social, environmental and cultural aspects, the Smart City concept presents itself as a solution for the present and the future of cities (ITU-T, 2016), also influencing the tourism industry, from which the Smart Tourism Destination emerges, which proposes to make the general experience of visitors more fun, efficient and convenient (BOES; BUHALIS; INVERSINI, 2015) . The objective of this thesis is to understand how the attributes of Smart Cities (GIFFINGER et al., 2007) influence the brand of a city. Employing a mixed methods strategy, tourists perceptions of attributes were collected in ten Latin American capitals. Then, the initiatives and the communication of the cities were investigated, through the analysis of the websites and publications in the tourism profiles of the social network Instagram. Finally, Rio de Janeiro s trajectory towards becoming a Smart City and Smart Tourist Destination (BUHALIS; AMARANGGANA, 2014) was examined. The findings point to dissonances between what is perceived and what is communicated, indicating opportunities for public managers, branding and tourism professionals to add such attributes to the positioning of city brands, as well as to expand the scope of an Smart Tourism Destination, bringing it closer to the Smart City concept. The thesis contributes to studies on place branding, by investigating how the attributes of Smart Cities can influence the brands of cities or tourist destinations and with the design of tourist destinations, by identifying that the People dimension should be highlighted. Involving citizens in an intelligent culture and adopting the dimensions of Smart Cities as premises to direct the ideation of the strategic plan of cities in Latin America, can contribute to building their Smart Cities reputation.
