Charmless Hadronic B Decays at BABAR

We present several searches for charmless hadronic two-body and three-body decays of B mesons from electron-positron annihilation data collected by the BABAR detector near the Υ (4S) resonance. We report the preliminary branching fractions B(B → ππ) = (4.1± 1.0± 0.7)× 10, B(B → Kπ) = (16.7 ± 1.6 ± 1.3) × 10, B(B → ρπ) = (49 ± 13 −5) × 10, B(B → ηK) = (62± 18± 8)× 10, and present upper limits for nine other decays.
