Circumventing a no-go theorem established in 1977 by nonlinearly realized supersymmetry, the authors construct for the first time a pure (without additional fields) N=1 supergravity with positive cosmological constant. Besides the theoretical achievement, given the observational evidence for an accelerating universe, a simple version of de Sitter supergravity is of broad interest.
