A measurement of the spin of the Omega- hyperon produced through the exclusive 
process Xic0 --> Omega- K+
is presented using a total integrated luminosity of 116 fb-1 recorded with the
BABAR detector at the e+ e- asymmetric-energy B-Factory at SLAC.
Under the assumption that the Xic0 has spin 1/2, the angular distribution of the
Lambda from Omega- --> Lambda K- decay is inconsistent with all
half-integer Omega- spin values other than 3/2.
Lower statistics data for the process
Omegac0 --> Omega- pi+ from a 230 fb-1 sample
are also found to be consistent with Omega- spin 3/2.  If the
Xic0 spin were 3/2, an Omega- spin of 5/2 cannot be excluded.
