The four LEP experiments have searched for charginos and neutralinos in e{sup +}e{sup {minus}} collisions at {radical}(s)=161{minus}172GeV. Both R-parity conserving and R-parity violating searches have been performed. For the R-parity conserving case the selections are generally designed under the assumption that the lightest neutralino is the Lightest Supersymmetric Particle (LSP); however, the case of a gravitino LSP has also been considered. No evidence for either charginos or neutralinos has been found by any of the four LEP experiments. Limits on the production cross sections and masses of charginos and neutralinos have therefore been set. {copyright} {ital 1997 American Institute of Physics.}
