Književna nagrada Nebula, najznačajniji je dobitak za svakog pisca žanra u SAD-u. Dodjeljuje se od davne 1966. godine, pa premda sadrži i kategoriju za scenarij (kao Best dramatic presentation koja se od 2010. naziva po slavnome piscu Rayu Bradburyju), i dalje se Nebula doživljava prvenstveno kao književna nagrada koju dodjeljuje udruženje američkih pisaca f&sf-a (Science Fiction and Fantasy Writers of America – SFWA). Nagrade za radove objavljene u 2013. godini dodjelit će se na Nebula vikendu (obično negdje u svibnju), a dobitnici će biti odabrani prema glasanju članova SFWA iz paketa nominacija koji je nedavno objavljen:
