  Recently, it was suggested that a photospheric component that results from
the internal dissipation occurring in the optically thick inner parts of
relativistic outflows may be present in the prompt $\gamma$/X-ray emission of
gamma-ray bursts or X-ray flashes. We explore high-energy neutrino emission in
this dissipative photosphere model, assuming that the composition of the
outflow is baryon-dominated. We find that neutrino emission from proton-proton
collision process forms an interesting signature in the neutrino spectra. Under
favorable conditions for the shock dissipation site, these low-energy neutrinos
could be detected by ${\rm km^3}$ detectors, such as Icecube. Higher energies
($\ga10$ TeV) neutrino emission from proton-proton collision and photo-pion
production processes could be significantly suppressed for dissipation at
relatively small radii, due to efficient Bethe-Heitler cooling of protons
and/or radiative cooling of the secondary mesons in the photosphere radiation.
As the dissipation shocks continue further out, high energy neutrinos from
photo-pion production process becomes dominant.
