Falcon Heavy is a super heavy-lift launch vehicle with partial reusability that can carry cargo into Earth orbit and beyond. It is designed, manufactured and launched by American aerospace company SpaceX.

The rocket consists of a center core on which two Falcon 9 boosters are attached, and a second stage on top of the center core. Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System (SLS), and the fourth-highest capacity of any rocket to reach orbit, trailing behind the SLS, Energia and the Saturn V.

SpaceX conducted Falcon Heavy's maiden launch on 6 February 2018, at 20:45 UTC. As a dummy payload, the rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk, with a mannequin dubbed "Starman" in the driver's seat. The second Falcon Heavy launch occurred on 11 April 2019, and all three booster rockets successfully returned to Earth. The third Falcon Heavy launch successfully occurred on 25 June 2019. Since then, Falcon Heavy has been certified for the National Security Space Launch (NSSL) program.

Falcon Heavy was designed to be able to carry humans into space beyond low Earth orbit, although as of February 2018, SpaceX does not intend to transport people on Falcon Heavy, nor pursue the human-rating certification process to transport NASA astronauts. Both Falcon Heavy and Falcon 9 are expected to eventually be superseded by the Starship super-heavy lift launch vehicle, currently being developed.
