The NIKA2 SZ Large Program (LPSZ) is devoted to the highangular resolution SZ mapping of a representative sample of SZ-selected clusters, at intermediate to high redshift, drawn from the catalogues of the Planck satellite and of the Atacama Cosmology Telescope. Central to this program is the synergy between SZ observations and X-ray data, utilizing measurements from NIKA2 and XMM-Newton or Chandra. The main goal of this program is to provide the community with unprecedented measurements of cluster maps at 150 and 260 GHz, thermodynamic profiles and integrated quantities. This paper describes the LPSZ scientific objectives, the first public release and its scienceready products, the published results on individual clusters and the upcoming publications on the full sample.
