The measurement of the production of Higgs boson pairs (HH) at the LHC allows the exploration
of the Higgs boson interaction with itself, which is a fundamental test of the Standard Model
theory. The most recent results from the CMS collaboration on measurements of non-resonant
HH production using different final states and their combination using the data set collected by
the CMS experiment at a centre of mass energy of 13 TeV will be presented here.
