The invention provides a launch vehicle upper-stage propulsion system and a launch vehicle. The system is characterized in that an outlet end of a supercharging device is connected with an air inlet end of a propellant storage tank, a control air inlet end of an upper-stage orbit control engine and an inlet end of a basic-stage control air separation connector; a liquid outlet end of the propellant storage tank is connected with a propellant inlet end of the upper-stage orbit control engine, a propellant inlet end of the upper-stage attitude control engine and an inlet end of a basic-stage propellant separation connector; an outlet end of the basic-stage control air separation connector is connected with a control air inlet end of the basic-stage attitude control engine; and an outlet end of the basic-stage propellant separation connector is connected with the propellant inlet end of the basic-stage attitude control engine. According to the launch vehicle upper-stage propulsion system and the launch vehicle, the weight of the upper stage is reduced, the carrying capacity of the launch vehicle is remarkably improved, connecting assemblies are reduced, and the reliability of the launch vehicle is improved.
