This review presents the current state of work on QSO hosts and companions at redshifts above 1. This includes the properties of QSO host galaxies, such as size, scale length, and luminosity, and morphology, as they appear to change with redshift and radio activity. This leads to a view of how the properties of galaxies that host QSOs change with cosmic time. I also review studies of the galaxy companions to QSOs at higher redshifts, and studies of the emission line gas in and around higher redshift QSOs. These topics should see great progress in the next decade.
