We examine the Higgs triple coupling in MSSM and NMSSM under current constraints, which include the LHC measurements, Higgs data, B physics, electroweak precision observables, relic density and so on. The ratio λhhhMSSM/λhhhSM is above 0.97, due to the highly constrained parameter space. While the ratio λhhhNMSSM/λhhhSM can reach 0.1 under current constraints. The precise measurement in future collider will give a tighter constraint to the Higgs triple coupling in MSSM and NMSSM.
