We investigate the prospects for the discovery of neutral Higgs bosons with a pair of muons by direct searches at the CERN Large Hadron Collider (LHC) as well as by indirect searches in the rare decay B_s → μ⁺ μ^- at the Fermilab Tevatron and the LHC. Promising results are found for the minimal supersymmetric standard model, the minimal supergravity (mSUGRA) model, and supergravity models with non-universal Higgs masses (NUHM SUGRA). For \tan β \simeq 50, we find that (i) the contours for a branching fraction of B(B_s →μ⁺μ^-) = 1 x 10^-8 in the parameter space are very close to the 5σ contours for pp → bφ⁰ → b μ^+μ- + X, φ⁰ = h⁰, H⁰, A⁰ at the LHC with an integrated luminosity (L) of 30 fb^-1, (ii) the regions covered by B(B_s → μ⁺μ^-) ≥ 5 x 10^-9 and the discovery region for bφ⁰ → bμ⁺μ^- with 300 fb^-1 are complementary in the mSUGRA parameter space, (iii) in NUHM SUGRA models, a discovery of B(B_s → μ⁺μ^-) \simeq 5 x 10^-9 at the LHC will cover regions of the parameter space beyond the direct search for bφ⁰ → bμ⁺μ^- with L = 300 fb^-1.
