In this paper, we report a search for charmless hadronic decays of neutral $B$ mesons to $η^{'} K^{*} (892)^{0}$ . The results are based on a $711 {fb}^{- 1}$ data sample that contains $772 \times 10^{6} B \bar{B}$ pairs, collected at the $Y (4 S)$ resonance with the Belle detector at the KEKB asymmetric energy $e^{+} e^{-}$ collider. We observe the decay for the first time with a significance of 5.0 standard deviations and obtain its branching fraction $B [B^{0} \to η^{'} K^{*} (892)^{0}] = [2.6 \pm 0.7 (stat) \pm 0.2 (syst)] \times 10^{- 6}$ . We also measure the $C P$ -violating asymmetry as $A_{C P} [B^{0} \to η^{'} K^{*} (892)^{0}] = - 0.22 \pm 0.29 (stat) \pm 0.07 (syst)$ .
