I review progress in ultrahigh-energy cosmic ray physics focusing on
models developed for the interpretation of recent experimental results.
Emphasis is put on models aiming to explain the transition from
Galactic to extragalactic cosmic rays together with composition and
anisotropy data. I discuss the additional constraints arising, if these
sources contribute to the observed neutrino flux and, if time permits,
comment on the effect of extragalactic magnetic fields.
