CMS Higgs physics prospect at the HL-LHC

The CMS Collaboration continues to work actively on developing the physics program for the High-Luminosity LHC (HL-LHC). A factor of ten increase in the integrated luminosity compared to the initial LHC program, and new and improved detector components, open the door for refined study of the properties of the Higgs boson, including its self-coupling. This talk will discuss the CMS Higgs physics contributions to the Energy Frontier (EF) groups of Snowmass 2021.
