We study in next-to-leading order QCD hadronic penguin B decays in the Standard and two-Higgs-doublet models. Although the gluonic penguin dominates, we find the electroweak contribution non-negligible. In the Standard Model, the branching ratio for B → Xs ϕ is predicted to be in the range (0.6∼ 2)× 10-4. The ranges of branching ratios for B→ K ϕ, B→ K^*ϕ, and Bs→ ϕϕ are (0.4∼ 2)× 10-5, (0.2∼ 1)× 10-5, and (0.15∼ 0.5)× 10-5, respectively. The contribution from the charged Higgs boson in two Higgs doublet models depend on cotβ, and can be as large as 40%.
