We study the coupling of non-linear supersymmetry to supergravity. The goldstino nilpotent superfield of global supersymmetry coupled to supergravity is described by a geometric action of the chiral curvature superfield 𝓡 subject to the constraint (𝓡-λ)² with an appropriate constant λ. This constraint can be found as the decoupling limit of the scalar partner of the goldstino in a class of 𝓡 supergravity theories.
