  We study constraints on the radion mass and couplings in the Randall-Sundrum
model from the recent LHC data on the Standard Model (SM) Higgs boson searches.
When the radion is heavy enough so that it can decay into a pair of on-shell
Z-bosons, we find that the ZZ channel gives a stringent constraint. For
example, if the radion mass m_\phi is 200 GeV, the scale \Lambda_\phi which
characterizes the interactions of the radion with the SM fields must be larger
than 5 TeV. Even for m_\phi=1 TeV, we find that the lower bound on \Lambda_\phi
is 2 TeV.
