We report the observation of a near-threshold enhancement in the {omega}J/{psi} invariant mass distribution for exclusive B{yields}K{omega}J/{psi} decays. The results are obtained from a 253 fb{sup -1} data sample that contains 275x10{sup 6} BB pairs that were collected near the {upsilon}(4S) resonance with the Belle detector at the KEKB asymmetric energy e{sup +}e{sup -} collider. The statistical significance of the {omega}J/{psi} mass enhancement is estimated to be greater than 8{sigma}.
