Abstract: In this paper, we shall review the construction of N = 2 supergravity models exhibiting stable de Sitter vacua. These solutions represent the first instance of stable backgrounds with positive cosmological constant in the framework of extended supergravities (N greater than or equal to 2). After briefly reviewing the role of de Sitter spacetimes in inflationary cosmology, we shall describe the main ingredients which were necessary for the construction of gauged N = 2 supergravity models admitting stable solutions of this kind.
