We present off-shell N= 2 supergravity actions, which exhibit spontaneously broken local supersymmetry and allow for de Sitter vacua for certain values of the parameters. They are obtained by coupling the standard N= 2 supergravity-matter systems to the Goldstino superfields introduced in arXiv:1105.3001 and arXiv:1607.01277 in the rigid supersymmetric case. These N= 2 Goldstino superfields include nilpotent chiral and linear supermultiplets. We also describe a new reducible N= 1 Goldstino supermultiplet.
