We have searched for two-body charmless hadronic decays of {ital B} mesons. Final states include {pi}{pi}, {ital K}{pi}, and {ital KK} with both charged and neutral kaons and pions: {pi}{rho}, {ital K}{rho}, and {ital K}{sup {asterisk}}{pi}; and {ital K}{phi}, {ital K}{sup {asterisk}}{phi}, and {phi}{phi}. The data used in this analysis consist of 2.6{times}10{sup 6} {ital B{bar B}} pairs produced at the {Upsilon}(4{ital S}) taken with the CLEO II detector at the Cornell Electron Storage Ring (CESR). We measure the branching fraction of the sum of {ital B}{sup 0}{r_arrow}{pi}{sup +}{pi}{sup {minus}} and {ital B}{sup 0}{r_arrow}{ital K}{sup +}{pi}{sup {minus}} to be (1.8{sub {minus}}{sub 0}{sub .}{sub 5}{sub {minus}}{sub 0}{sub .}{sub 3}{sup +}{sup 0}{sup .}{sup 6}{sup +}{sup 0}{sup .}{sup 2}{plus_minus}0.2){times}10{sup {minus}}{sup 5}. In addition, we place upper limts on individual branching fractions in the range from 10{sup {minus}}{sup 4} to 10{sup {minus}}{sup 6}. {copyright} {ital 1996 The American Physical Society.}
