The electric dipole moment (EDM) of the top quark is calculated in a modelwith a vector like multiplet which mixes with the third generation in anextension of the MSSM. Such mixings allow for new CP violating phases.Including these new CP phases, the EDM of the top in this class of models iscomputed. The top EDM arises from loops involving the exchange of the W, the Zas well as from the exchange involving the charginos, the neutralinos, thegluino, and the vector like multiplet and their superpartners. The analysis ofthe EDM of the top is more complicated than for the light quarks because themass of the external fermion, in this case the top quark mass cannot be ignoredrelative to the masses inside the loops. A numerical analysis is presented andit is shown that the top EDM could be close to $10^{-19} ecm$ consistent withthe current limits on the EDM of the electron, the neutron and on atomic EDMs.A top EDM of size $10^{-19}ecm$ could be accessible in collider experimentssuch as the ILC.
