Studies of quarkonium production in heavy-ion collisions can be used for probing QGP properties.

In this work, recent quarkonium measurements performed by ALICE in Pb-Pb collisions at \(\sqrt{s_{\mathrm{NN}}}~=~5.02\) TeV will be discussed. Preliminary measurements of the inclusive J/\(\psi\) \(R_{\rm AA}\) measured at both forward and midrapidity will be presented.
