We study the minimal gauged U(1){sub B-L} supersymmetric model and show that it provides an attractive theory for spontaneous R-parity violation. Both U(1){sub B-L} and R parity are broken by the vacuum expectation value of the right-handed sneutrino (proportional to the soft supersymmetry masses), thereby linking the B-L and soft SUSY scales. In this context we find a consistent mechanism for generating neutrino masses and a realistic mass spectrum, all without extending the Higgs sector of the minimal supersymmetry standard model. We discuss the most relevant collider signals and the connection between the Z{sup '} gauge boson and R-parity violation.
