Tendenza (in Italian, tendency) was an Italian architectural group with a neo-rationalist style that emerged in the 1970s, in parallel to the American group Five Architects. It was mainly composed of Aldo Rossi, Giuseppe Samonà, Giorgio Grassi, Massimo Scolari"), Ezio Bonfanti") and Carlo Aymonino.

In opposition to pop and high-tech architecture, the Tendenza group sought to continue the rationalist tradition of Italian architecture before the Second World War. Ideologically, they were nourished by the functionalist theory of Aldo Rossi, presented in The architecture of the city (1966), where he defended the return to the classicist tradition and architectural design based on logical principles. Thus, for the members of the group, architecture must direct the urban growth of cities, detached from any other discipline in a specific autonomy that purges architecture of extra-architectural dependencies. In this new relationship between architecture and the city, the collective uses of urban morphology will define the new architectural typologies to follow.
