The main goal of the ALICE experiment is to study the properties of the strongly- interacting matter, usually referred to as the Quark-Gluon Plasma (QGP), created in high-energy heavy-ion collisions. Heavy quarks, i.e. charm and beauty quarks, are good probes of the QGP as they are produced in the early stage of the collisions and witness the entire space-time evolution of the system. In ALICE, open heavy-flavour production is studied through the measurements of the heavy-flavour decay leptons (electrons and muons) at central and forward rapidity and via the reconstruction of D-meson hadronic decays at central rapidity. An overview of the open heavy-flavour production with ALICE in pp, p-Pb, Xe-Xe and Pb-Pbcollisions will be presented. I will discuss the production cross sections, modifications of the transverse momentum distributions, azimuthal anisotropic emissions and correlations with hadrons in comparison with various theoretical predictions.
