A '''jet pack''', '''rocket belt''', '''rocket pack''' or '''flight pack''' is a device worn as a [[backpack]] which uses [[jet (fluid)|jets]] to [[Propulsion|propel]] the wearer through the air. The concept has been present in [[science fiction]] for almost a century and the first working experimental devices were demonstrated in the 1960s.

Jet packs have been developed using a variety of mechanisms, but their uses are limited because of factors including the Earth's atmosphere, gravity, the low energy density of extreme fuels,{{clarify|date=November 2024}} and the human body not being suited to flight, so they are principally used for stunts.

A practical use for the jet pack has been in extra-vehicular activities for astronauts because of the weightlessness and lack of friction-creating atmosphere in orbit. The term '''jet suit''' is used for a system incorporating a jet pack and associated jets attached to the arms to increase manoeuvrability (e.g. the [[Daedalus Flight Pack]]).
