We search for a charged partner of the X(3872) in the decay B{yields}X{sup -}K, X{sup -}{yields}J/{psi}{pi}{sup -}{pi}{sup 0}, using 234x10{sup 6} BB events collected at the {upsilon}(4S) resonance with the BABAR detector at the PEP-II e{sup +}e{sup -} asymmetric-energy storage ring. The resulting product branching fraction upper limits are B(B{sup 0}{yields}X{sup -}K{sup +},X{sup -}{yields}J/{psi}{pi}{sup -}{pi}{sup 0})<5.4x10{sup -6} and B(B{sup -}{yields}X{sup -}K{sup 0},X{sup -}{yields}J/{psi}{pi}{sup -}{pi}{sup 0})<22x10{sup -6} at the 90% confidence level.
