Earth Star Voyager is the name of a science fiction television movie shown on the Wonderful World of Disney in 1988. The show aired as a two-part pilot, but was never picked up for a series and has not been released on DVD, although a fan base for the pilot has grown over the years.

In the late 21st century, planet earth's natural resources are near depletion, and problems like acid rain and limited breathable oxygen abound. In response to the environmental decline, the Earth Star Voyager is created as an experimental space ship that sends the brightest young crewmen and women on a quest to find a new planet that human beings can colonize. Along the way, they find the long lost Jacob 'Jake' Brown, find a world with hostile aliens, and learn that the star craft's top secret purpose was not just a peaceful space exploration mission, but also potentially the critical piece of a super weapon.

In 2088, when the Earth is heavily polluted and the atmosphere is becoming unbreathable, title starship is launched to investigate whether a planet in a solar system some eighteen light years from Earth would be suitable as a new home for the human race, which would migrate there en mass, a process that would take several decades, as forty years would be required to build the fleet of starships needed. This planet, called Demeter (the Greek goddess of corn, grain and the harvest) was discovered by an earlier mission which took some fuzzy video footage and sent it back to Earth before vanishing without trace. As the round trip would take twenty-five years at near-light speed, many of the crew members that have been selected are teens and young adults. In many ways their voyage is a leap into the unknown as their mission is plagued by a host of problems shortly after they leave Earth behind.
