  Selected recent results from the H1 and ZEUS experiments are reviewed,
illustrating some of the many facets of ``meson physics'' at the HERA ep
collider. The results cover exclusive elastic and proton-dissociative
diffractive vector meson production and comparisons with recent theoretical
calculations show that perturbative QCD models are successful in describing
these processes when at least one of the involved scales have large values.
Furthermore a search for odderon induced exclusive photoproduction of
pseudoscalar and tensor mesons is described; upper limits for the cross
sections are below recent theoretical predictions. Finally the status of open
charm meson spectroscopy in inclusive final states is reported.
