We report an analysis of charmless hadronic decays of neutral B mesons to the final state K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}}, using a data sample of (465{+-}5)x10{sup 6} BB events collected with the BABAR detector at the {Upsilon}(4S) resonance. We observe an excess of signal events with a significance of 5.2 standard deviations including systematic uncertainties and measure the branching fraction to be B(B{sup 0}{yields}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}})=(3.2{+-}0.5{+-}0.3)x10{sup -6}, where the uncertainties are statistical and systematic, respectively.
