Experiment and theory related to the neutral weak current of the nucleon is briefly reviewed. Completed measurements include those of the SAMPLE (MIT-Bates), HAPPEX (JLab) and PVA4 (Mainz) experiments. The future plans for the latter two experiments and those for the G0 experiment (JLab) are also discussed. The review includes discussion of the physics associated with the contributions of different quark flavors to the nucleon vector currents, as well as that associated with the axial vector currents.
