Collider has published a list of ten science fiction novels that won both the Hugo and Nebula Awards, the two most prestigious prizes in speculative fiction, voted on respectively by members of the World Science Fiction Convention and the Science Fiction and Fantasy Writers Association. Achieving both is considered a mark of enduring classic status, and the selected novels span decades and subgenres, from hard sci-fi to military fiction to philosophical space opera.

The list highlights books such as Larry Niven's "Ringworld" (1970), which introduced the influential concept of a vast artificial ring-shaped structure encircling a star; Orson Scott Card's "Ender's Game" (1985), about child soldiers trained to fight an alien invasion; and Ann Leckie's "Ancillary Justice" (2013), a space opera narrated by the fragmented consciousness of a former warship exploring themes of identity and empire.
