The Nebula Awards annually recognize the best works of science fiction or fantasy published in the United States. The awards are organized and awarded by the Science Fiction and Fantasy Writers of America (SFWA), a nonprofit association of professional science fiction and fantasy writers. They were first given in 1966 at a ceremony created for the awards, and are given in four categories for different lengths of literary works. A fifth category for film and television episode scripts was given 1974–78 and 2000–09, and a sixth category for game writing was begun in 2018. The rules governing the Nebula Awards have changed several times during the awards' history, most recently in 2010. The SFWA Nebula Conference, at which the awards are announced and presented, is held each spring in the United States. Locations vary from year to year.
The Andre Norton Nebula Award for Middle Grade and Young Adult Fiction (formerly the Andre Norton Award for Young Adult Science Fiction and Fantasy) is an annual award presented by the Science Fiction and Fantasy Writers of America (SFWA) to the author of the best young adult or middle grade science fiction or fantasy book published in the United States in the preceding year. It is named to honor prolific science fiction and fantasy author Andre Norton (1912–2005), and it was established by then SFWA president Catherine Asaro and the SFWA Young Adult Fiction committee and announced on February 20, 2005. Any published young adult or middle grade science fiction or fantasy novel is eligible for the prize, including graphic novels. There is no limit on word count. The award was originally not a Nebula Award, despite being presented along with them and following the same rules for nominations and voting, but in 2019 SFWA announced that the award was considered a Nebula category.
