We are grateful for the excellent luminosity and machine conditions provided by our PEP-II colleagues, and for the substantial dedicated effort from the computing organizations that support BABAR. The collaborating institutions wish to thank SLAC for its support and kind hospitality.

We present the results of searches for B decays to charmless final states involving ϕ, f_0(980), and charged or neutral ρ mesons. The data sample corresponds to 384×10^6 BB̅ pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy e^̅+e^- collider at SLAC. We find no significant signals and determine the following 90% confidence level upper limits on the branching fractions, including systematic uncertainties: B(B^0→ϕϕ)<2.0×10^(-7), B(B+→ϕρ^+)<30×10^(-7), B(B^0→ϕρ^0)<3.3×10^(-7), B[B^0→ϕf_0(980)]×B[f_0(980)→π^+π^-]<3.8×10^(-7), and B[B^0→f_0(980)f_0(980)]×B[f_0(980)→π^+π^-]×B[f_0(980)→K^+K^-]<2.3×10^(-7).
