  We propose a modification to the standard hybrid inflation model
\cite{Linde:1993cn}, that connects a successful hybrid inflation scenario to
the standard model Higgs sector, via the electroweak vacuum stability. The
proposed model results in an effective inflation potential of a hilltop-type,
with both the trans-Planckian and sub-Planckian inflation regimes consistent
with the recent Planck/BICEP combined results. Reheating via the inflation
sector decays to right-handed neutrinos is considered. An upper bound on the
reheating temperature $T_{\rm R} \lsim 2\times 10^{11}~(1\times 10^{13})$ GeV,
for large~(small) field inflation, will suppress contributions from one-loop
quantum corrections to the inflation potential. This may push the neutrino
Yukawa couplings to be ${\cal O}(1)$ and affect the vacuum stability. We show
that the couplings of the SM Higgs to the inflation sector can guarantee the
electroweak vacuum stability up to the Planck scale. The so-called hybrid
Higgs-inflaton model leads to a positive correction for the Higgs quartic
coupling at a threshold scale, which is shown to have a very significant effect
in stabilizing the electroweak vacuum. We find that even with ${\cal O}(1)$
neutrino Yukawa couplings, threshold corrections leave the SM vacuum stability
intact.
