We report the results of the first search for the decay B0s→η′K0S using 121.4 fb-1 of data collected at the Γ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We observe no signal and set a 90% confidence-level upper limit of 8.16×10-6 on the B0s→η′KS0 branching fraction.
