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) x 10{sup 6} B{bar B} 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 {Beta}(B{sup 0} {yields} K{sub S}{sup 0}K{sup {+-}}{pi}{sup {-+}}) = (3.2 {+-} 0.5 {+-} 0.3) x 10{sup -6}, where the uncertainties are statistical and systematic, respectively.
