Le Guin has won dozens of annual "year's best" literary awards. For novels alone she has won five Locus, four Nebula, two Hugo, and one World Fantasy Award. (The Dispossessed won the Locus, Nebula, and Hugo.) She has also won those four awards in short fiction categories, although she turned down a Nebula award for her novelette The Diary of the Rose in protest at the Science Fiction Writers of America's treatment of Stanislaw Lem. Her nineteen Locus Awards, voted by magazine subscribers, are more than any other writer has received. Her third Earthsea novel, The Farthest Shore won the 1973 National Book Award for Young People's Literature and she has been a finalist for ten Mythopoeic Awards, nine in Fantasy and one for Scholarship. Unlocking the Air and Other Stories was one of three finalists for the 1997 Pulitzer Prize for Fiction.
Recognizing her stature in the speculative fiction genre, Le Guin was the Professional Guest of Honor at the 1975 World Science Fiction Convention in Melbourne, Australia. That year she was also named the sixth Gandalf Award Grand Master of fantasy. The Science Fiction Research Association (SFRA) gave her its Pilgrim Award in 1989 for her "lifetime contributions to SF and fantasy scholarship". At the 1995 World Fantasy Convention she won the World Fantasy Award for Life Achievement, a judged recognition of outstanding service to the fantasy field. The Science Fiction and Fantasy Hall of Fame inducted her in 2001, its sixth class of two deceased and two living writers. The Science Fiction and Fantasy Writers of America made her its 20th Grand Master in 2003.
In April 2000 the U.S. Library of Congress made Le Guin a Living Legend in the "Writers and Artists" category for her significant contributions to America's cultural heritage. In 2002 she won a PEN/Malamud Award for "excellence in a body of short fiction". In 2004 she received two American Library Association honors for her lasting contributions: for young adult literature, the annual Margaret A. Edwards Award; for children's literature, selection to deliver the annual May Hill Arbuthnot Lecture. The annual Edwards Award recognizes one writer and a particular body of work; the 2004 panel cited six works published from 1968 to 1990: A Wizard of Earthsea, The Tombs of Atuan, The Farthest Shore, and Tehanu (the first four Earthsea books), The Left Hand of Darkness and The Beginning Place. The panel said that Le Guin "has inspired four generations of young adults to read beautifully constructed language, visit fantasy worlds that inform them about their own lives, and think about their ideas that are neither easy nor inconsequential."
At its 2009 convention, the Freedom From Religion Foundation awarded the Emperor Has No Clothes Award to Le Guin. The FFRF describes the award as "celebrating 'plain speaking' on the shortcomings of religion by public figures".[a]
In 2014, Le Guin was awarded the Medal for Distinguished Contribution to American Letters by the National Book Foundation, a lifetime achievement award. Her acceptance speech, which criticized Amazon as a "profiteer", and praised her fellow authors of fantasy and science fiction, was widely considered the highlight of the ceremony.
