This article aims to define the psychosocial profile of farmers who sell their products in Agroecological Fair Olinda, defining them as their degree of entrepreneurship, their motivations and according to the principles of sustainability. Initially it was discussed in the theoretical topics such as entrepreneurship, entrepreneurial profile, agroecological fairs and culture of sustainability, positioning ideologically concepts adopted by the authors of this article. Then a structured interview was conducted with producers who participate in the Fair, with its very broad scope in order that all the stalls were covered, being interviewed by a producer tent. In general, the results showed that producers are men, mostly poorly educated, seeking growth beyond economic quality of life for their families and their clients. It also became clear that their activity is a process of innovation, and, under our concept, producers are characterized as entrepreneurs and their activities directly contribute to a culture of sustainability, which can be defined as sustainable entrepreneurs.
