<jats:p>Promoting accessibility in tourism can impact on other areas, including sustainable mobility, social inclusion, and territorial marketing, since it implies taking the needs of all people into account to access tourism products and services, including those with permanent or temporary disabilities. Smart cities may change the way people experience their surroundings and their ability to provide contextual services is a key aspect to make cities more accessible, comprehensible, and enjoyable. The systematic review reported by the present chapter aimed to identify relevant research studies supported by smart cities infrastructures with an impact on accessible tourism. The literature search and the analysis of the retrieved articles were performed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The results identify the most relevant achievements related to accessible tourism in the context of smart cities, including the types of smart services being developed and their maturity level. </jats:p>
