In this talk, the latest results from CMS on searches for RP violating supersymmetry or Leptoquarks are presented using 20/fb of data from the 8 TeV LHC run. Results across a wide range of final states are reviewed, and interpreted in the context of a variety of models of new physics including leptoquarks, gluinos, squarks, neutralinos, charginos and sleptons.
