The PHENIX experiment at the Relativistic Heavy Ion Collider has measured low-mass vector-meson, ω, ρ, and ϕ, production through the dimuon decay channel at forward rapidity (1.2<|y|<2.2) in p+p collisions at s=200  GeV. The differential cross sections for these mesons are measured as a function of both pT and rapidity. We also report the integrated differential cross sections over 1<pT<7  GeV/c and 1.2<|y|<2.2: dσ/dy(ω+ρ→μμ)=80±6(stat)±12(syst)  nb and dσ/dy(ϕ→μμ)=27±3(stat)±4(syst)  nb. These results are compared with midrapidity measurements and calculations.
