Rhysling Award

The Rhysling Awards are an annual award given for the best science fiction, fantasy, or horror poem of the year. The award name was dubbed by Andrew Joron in reference to a character in a science fiction story: the blind poet Rhysling, in Robert A. Heinlein's short story "The Green Hills of Earth". The award is given in two categories: "Best Long Poem", for works of 50 or more lines, and "Best Short Poem", for works of 49 or fewer lines. The nominees for each year's Rhysling Awards are chosen by the members of the Science Fiction Poetry Association (SFPA). Each member may nominate one work for each of the categories. Until 2022, all nominated works were compiled into an anthology called The Rhysling Anthology, and members of the Association would then vote on the final winners.
