  Blazar emission models are usually divided into two big families, leptonic
and hadronic, according to the particles which are responsible for the
gamma-ray component of their spectral energy distributions. Even though
leptonic models have been successful in explaining the gamma-ray emission from
most blazars, hadronic models still present an intriguing alternative. They
have the unique advantage to link the emission of photons, neutrinos, and
cosmic rays from the astrophysical source. We have developed a stationary
one-zone lepto-hadronic code to model the emission from blazars in both
leptonic and hadronic scenarios. In this contribution we focus on hadronic
modeling of a few selected TeV blazars of the BL Lac type and the radio galaxy
Centaurus A detected by Cherenkov telescopes. We study in particular their
associated neutrino emission, for different hadronic scenarios, and how it
compares to the sensitivity of current neutrino detectors.
