The ITS launch vehicle is a privately funded orbital launch vehicle being developed by SpaceX. The initial design objective of the vehicle is to launch a variety of SpaceX Interplanetary Transport System missions to Mars and other destinations in the beyond-Earth-orbit portion of the Solar System. Design work on the vehicle began in 2012 and first launch is not expected before the 2020s.

The ITS launch vehicle is described as a two-stage rocket. Its first stage will be powered by 42 Raptor rocket engines—also designed and manufactured by SpaceX—operating on densified methane/oxygen propellants that have not been widely used as rocket propellants in the past. Like the Falcon 9 orbital launch vehicle that preceded it, the ITS launch vehicle's first stage is designed to be reusable, following a return to the launch site and vertical landing following each launch. New on this vehicle will be full reusability of even the second-stage and spacecraft as well. The large payload capacity of the launch vehicle places it into the super-heavy lift class, with the ability to place 300 tonnes (660,000 lb) into low Earth orbit in reusable configuration and 550 tonnes (1,210,000 lb) in expendable mode.
