  We construct a simple class of N=2 gauged supergravity theories that admit
metastable de Sitter vacua, generalizing the recent work done in the context of
rigid supersymmetry. The setup involves one hypermultiplet and one vector
multiplet spanning suitably curved quaternionic-Kahler and special-Kahler
geometries, with an Abelian gauging based on a single triholomorphic isometry,
but neither Fayet-Iliopoulos terms nor non-Abelian gauge symmetries. We
construct the most general model of this type and show that in such a situation
the possibility of achieving metastable supersymmetry breaking vacua crucially
depends on the value of the cosmological constant V relative to the gravitino
mass squared m_{3/2}^2 in Planck units. In particular, focusing on de Sitter
vacua with positive V, we show that metastability is only possible when V >=
2.17 m_{3/2}^2. We also derive an upper bound on the lightest scalar mass in
this kind of model relative to the gravitino mass m_{3/2} as a function of the
cosmological constant V, and discuss its physical implications.
