  Supersymmetry with breaking of R-parity provides an attractive way to
generate neutrino masses and lepton mixing angles in accordance to present
neutrino data. We review the main theoretical features of the bilinear R-parity
breaking (BRpV) model, and stress that it is the simplest extension of the
minimal supersymmetric standard model (MSSM) which includes lepton number
violation. We describe how it leads to a successful phenomenological model with
hierarchical neutrino masses. In contrast to seesaw models, the BRpV model can
be probed at future collider experiments, like the Large Hadron Collider or the
Next Linear Collider, since the decay pattern of the lightest supersymmetric
particle provides a direct connection with the lepton mixing angles determined
by neutrino experiments.
