  We present measurements of the time-dependent CP-violating asymmetries in B0
--> K0S K0S K0S decays based on 384 million Y(4S) decays collected with the
BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We obtain the
CP asymmetry parameters C = 0.02 +/- 0.21 +/- 0.05 and S = -0.71 +/- 0.24 +/-
0.04, where the first uncertainties are statistical and the second systematic.
These results are consistent with standard model expectations.
