  Quarkonium production as a function of the charged-particle multiplicity
could provide an insight into particle production processes at the partonic
level in hadronic collisions. It is believed that multiple partonic
interactions play an important role in particle production and affect both soft
and hard processes. The study of correlations between quarkonia and
charged-particle multiplicity may provide information about this. In this
contribution, ALICE measurements of J$/\psi$ and $\Upsilon$ production as a
function of charged-particle multiplicity are presented for pp collisions at
center-of-mass energies $\sqrt{s}$ = 5.02 and 13 TeV. A similar measurement
performed in p\textendash Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 8.16 TeV at
both forward and backward rapidity is also discussed.
