We estimate the size of the CP-violating rate asymmetry for the decay Omega^- -> Cascade + pion. Within the standard model we find a value of 2 x 10^(-5), and it could be as much as ten times larger if new physics is responsible for CP violation. Even though our calculation suffers from the usual uncertainty in the estimate of hadronic matrix elements, we find a rate asymmetry that is significantly larger than the corresponding one for octet-hyperon decays.
