Saturn Award for Best Performance by a Younger Actor

The Saturn Award for Best Performance by a Younger Actor is one of the annual awards given by the American professional organization the Academy of Science Fiction, Fantasy and Horror Films. The Saturn Awards are the oldest film-specialized awards to reward science fiction, fantasy, and horror achievements (the Hugo Award for Best Dramatic Presentation, awarded by the World Science Fiction Society who reward science fiction and fantasy in various media, is the oldest award for science fiction and fantasy films).

The category was first introduced for the 1984 film year, specifically to reward young actors and actresses in films, and was the first acting award of the Academy to reward both males and females. Tom Holland is the only actor to have won it three times, to have won it three years in a row, and to have won three times for the same role. Haley Joel Osment and Chloë Grace Moretz have each won the award twice. Moretz and Daniel Radcliffe have received the most nominations, with 5 each. Christina Ricci, Elijah Wood, Kirsten Dunst, and Tobey Maguire are the only actors to have won both Best Performance by a Younger Actor and later a Saturn Award for adults.
