The status and results of the searches for non-resonant and resonant Higgs boson pair production at the LHC are presented. The analyses are performed using partial and full Run-2 proton-proton collision datasets recorded at $\mathrm{\sqrt{s}=}$13 TeV, corresponding to an integrated luminosity of up to about 140 fb$^{-1}$. The most sensitive results obtained by ATLAS and CMS are reported.
