We report an analysis of charmless hadronic decays of charged B mesons to the final state K{sup +}{pi}{sup 0}{pi}{sup 0}, using a data sample of 470.9 {+-} 2.8 million B{bar B} events collected with the BABAR detector at the {Upsilon}(4S) resonance. We observe an excess of signal events with a significance above 10 standard deviations including systematic uncertainties and measure the branching fraction to be {Beta}(B{sup +}{yields}K{sup +}{pi}{sup 0}{pi}{sup 0}) = (15.5 {+-} 1.1 {+-} 1.6) x 10{sup -6}, where the uncertainties are statistical and systematic, respectively.
