Silversun is a science fiction children's television series made in Australia by the Australian Broadcasting Corporation (ABC). The show features the adventures of the adolescent members of the crew of the Star Runner, an interstellar spaceship carrying a cargo of 550 cryonically suspended colonists ("cryons") to their new home, the Silver Sun.

In the year 2052, the Star Runner and its crew are two years into their 90-year journey to a livable planet 45 light years from Earth. The crew's goal is to get the "New Settlers" safely to the Silver Sun and begin a colony there. Because of the 90-year-length of the journey, the crew are mostly teenagers who will take over command of the Star Runner as the adults get older.
