Using data samples with an integrated luminosity of 4.67 fb(-1) collected by the BESIII detector operating at the BEPCII Collider, we search for the process e(+)e(-) -> eta 'psi(2S) at center-of-mass energies from 4.66 to 4.95 GeV. No significant signal is observed, and upper limits for the Born cross sections sigma(B)(e(+)e(-) -> eta 'psi(2S)) at the 90% confidence level are determined.
