Palavras-chave: Gestão do conhecimento; Autenticidade; Liderança autêntica.Abstract: Leadership plays an important role in creating value, innovation and setting strategies of management and implementation of knowledge. In the context of leadership, there is a discussion about ethics and authenticity, especially after the scandals involving senior leaders of some organizations, mainly the American Enron and Arhur Endersen. The aim of this paper is to present the theory of authentic leadership, based on the assumptions of authenticity and strong ethical/moral values. It is an interesting conduct for knowledge-intensive organizations, since they are concerned with creating a positive organizational environment, focused on real and sustainable performance. Ethics and authenticity in relationships may favor knowledge creation and sharing. There are many possibilities for future (empirical) studies to analyze the authentic leadership and its development in social and organizational environments.
