A '''generation ship''', '''generation starship''' or '''world ship''',<ref name="hein-pak-putz-revisited" /> is a hypothetical type of [[interstellar ark]] [[starship]] that travels at sub-[[speed of light|light speed]]. Since such a ship might require hundreds to thousands of years to reach nearby stars, the original occupants of a generation ship would grow old and die, leaving their descendants to continue traveling.
