 note = {The process e^+e^- →K^+K^-J/Ψ is observed for the first time via initial-state radiation. The cross section of e^+e^- → K^+K^-J/Ψ for center-of-mass energies between threshold and 6.0 GeV is measured using 673 fb^{-1} of data collected with the Belle detector on and off the Υ(4S) resonance. No significant signal for Y(4260)→ K^+K^-J/Ψ is observed, and we determine B(Y(4260)→ K^+K^-J/Ψ)Γ(Y(4260)→ e^+e^-)<1.2 eV/c^2 at a 90% confidence level. We also find evidence for e^+e^ → K\O\S K\O\SJ/Ψ in the same data sample.},
