The Rhysling Awards are a prize given each year for the best poem from science fiction, fantasy, or horror. Most awards for writing are named for the creator of the award, the subject of the award, or an important person. The Rhyslings are named for a character in a science fiction story: the blind poet Rhysling, in Robert A. Heinlein's short story "The Green Hills of Earth". Two awards are given: "Best Long Poem", for poetry of 50 or more lines, and "Best Short Poem", for works of 49 or fewer lines.
