Recent results from CMS on searches for the electroweak production of supersymmetry particles are reviewed. The searches are performed in final states with three or four leptons, two same-sign leptons, two opposite-sign-same-flavor leptons with two jets, and two non-resonant opposite-sign leptons. The results are based on the full 2012 dataset which comprises 19.5 fb - 1 of proton-proton collisions at p s = 8 TeV. The observed yields agree with the standard model expectations and are used to place limits on the rates of the direct production of charginos, neutralinos and sleptons.
