We present the first observation of the decay B{sup +} {yields} {rho}{sup +}K{sup 0}, using a data sample of 348 fb{sup -1} collected at the {Upsilon}(4S) resonance with the BABAR detector. The branching fraction and charge asymmetry are measured to be (8.0{sub -1.3}{sup +1.4} {+-} 0.5) x 10{sup -6} and (-12.2 {+-} 16.6 {+-} 2.0)%, respectively, where the first uncertainty is statistical and the second is systematic. The significance of the observed branching fraction, including systematic uncertainties, is 7.9 standard deviations.
