  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
$\lambda^{\rm MSSM}_{hhh}/\lambda^{\rm SM}_{hhh}$ is above 0.97, due to the
highly constrained parameter space. While the ratio $\lambda^{\rm
NMSSM}_{hhh}/\lambda^{\rm SM}_{hhh}$ 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.
