Four different supersymmetric models based on SU(2)L\ifmmode×\else\texttimes\fiU(1)R\ifmmode×\else\texttimes\fiU(1)_B\ensuremath-L and SU(2)L\ifmmode×\else\texttimes\fiSU(2)R\ifmmode×\else\texttimes\fiU(1)_B\ensuremath-L gauge symmetry groups are studied. U(1)_B\ensuremath-L symmetry is broken spontaneously by a vacuum expectation value (VEV) of a sneutrino field. The right-handed gauge bosons may obtain their mass solely by a sneutrino VEV. The physical charged lepton and neutrino are mixtures of gauginos, Higgsinos and lepton interaction eigenstates. Explicit formulas for masses and mixings in the physical lepton fields are found. The spontaneous symmetry-breaking mechanism fixes the trilinear R-parity breaking couplings. Only some special R-parity breaking trilinear couplings are allowed. There is a potentially large trilinear lepton number breaking coupling --- which is unique to left-right models --- that is proportional to the SU(2)R gauge coupling gR. The couplings are parametrized by few mixing angles, making spontaneous R-parity breaking a natural ``unification framework'' for R-parity breaking couplings in supersymmetric left-right models.
