We present preliminary results of a search for several exclusive charmless hadronic B decays from electron-positron annihilation data collected by the BABAR detector near the Y(4S) resonance. These include three-body decay modes with final states h+/-h-/+h+/- and h+/-h-/+pi0, and quasi-two-body decay modes with final states X0 h and X0 K0S, where h = pi or K and X0 = eta^' or omega. We find B(B0 --> rho^(-/+)pi^(+/-)) = (49+/-13+6-5) x 10-6 and B(B+ --> eta^' K+) = (62+/-18+/-8) x 10-6 and present upper limits for eight other decays.
