  ALICE (A Large Ion Collider Experiment) is the LHC experiment dedicated to
the investigation of the nature and the properties of the Quark-Gluon Plasma
(QGP) using heavy-ion collisions. Among its characteristics, excellent particle
identification capabilities stand out, which are a basic requirement to address
QGP physics. The ALICE particle identification performance will be reviewed in
this paper, focusing in particular on the LHC Run 2 period.
