Results on the recent measurements of the electroweak-boson production performed by the ALICE Collaboration are reported. The W±-boson production was measured at midrapidity in pp collisions at √S = 13 TeV, via the electronic decay of the boson. It was also measured in association with a hadron emitted back-to-back with respect to the electron. In heavy-ion collisions, the W±- and Z0-boson production was measured at forward rapidity in p–Pb collisions at √SNN = 8.16 TeV and Pb–Pb collisions at √SNN = 5.02 TeV, in their muonic decay channel. Measurements in pp collisions shed light on multiple parton interactions and colour reconnection mechanisms. In heavy-ion collisions the measurements of electroweak bosons allow to probe the initial state of the collision.
