We give holomorphic Chern-Simons-like action functionals on supertwistorspace for self-dual supergravity theories in four dimensions, dealing withN=0,...,8 supersymmetries, the cases where different parts of the R-symmetryare gauged, and with or without a cosmological constant. The gauge group isformally the group of holomorphic Poisson transformations of supertwistor spacewhere the form of the Poisson structure determines the amount of R-symmetrygauged and the value of the cosmological constant. We give a formulation interms of a finite deformation of an integrable \dbar-operator on a supertwistorspace, i.e., on regions in CP^{3|8}. For N=0, we also give a formulation thatdoes not require the choice of a background.
