Flashing Swords! is a series of fantasy anthologies published by Dell Books from 1973 to 1981 under the editorship of Lin Carter, and revived under the editorship of Robert M. Price in 2020. It originally showcased the heroic fantasy work of the members of the Swordsmen and Sorcerers' Guild of America (SAGA), a somewhat informal literary group active from the 1960s to the 1980s, of which Carter was the guiding force. Most of the important sword and sorcery writers at the time of the group’s founding were members; later, membership was extended to other fantasy authors.

Linwood Vrooman Carter was an American author of science fiction and fantasy, as well as an editor, poet and critic. He usually wrote as Lin Carter; known pseudonyms include H. P. Lowcraft and Grail Undwin. He is best known for his work in the 1970s as editor of the Ballantine Adult Fantasy series, which introduced readers to many overlooked classics of the fantasy genre.
