We present results of supersymmetric (SUSY) particle searches from
the Collider Detector at Fermilab (CDF).  First we describe searches for a
charged Higgs boson and a stop squark, which could be produced in top quark
decays.  We also search for chargino-neutralino production using a trilepton
signature.  Finally, we investigate R-parity violating squark and LSP decay
modes which have been produced to accommodate the excess of high-Q^2 events at
HERA.  No evidence for SUSY is found, and limits are placed on these
processes.
