This paper will initially foreground some considerations about the definition of the concept of urban regeneration, presenting a review of the scientific literature about the origin of the concept and placing it in relation to other "re" phenomena and processes that have emerged as trends in the urban space: reurbanization, revitalization, restructuring, recomposition, renewal, rehabilitation, requalification etc. Secondly, a number of assumptions and characteristics of the urban regeneration process will be discussed, which are simultaneously principles that orient the theory and the practice of this process in urban planning, namely to be comprehensive, integrated, strategic, flexible, based on partnerships and promoting sustainability/resilience. Within this problematization, the evolution of the concept throughout the last five decades will also be addressed, according to various changes in the socio-economic and political-ideological context of urban space, from fordism to post-fordism, bearing in mind the main key actors and stakeholders as well as the leading strategies and concerns in urban politics.
