Flashing Swords! #4: Barbarians and Black Magicians is an anthology of fantasy stories, edited by Lin Carter. It was first published in hardcover by Nelson Doubleday in May 1977 as a selection in its Science Fiction Book Club, and in paperback by Dell Books in November 1977.^[1]

The book collects five heroic fantasy novelettes by members of the Swordsmen and Sorcerers' Guild of America (SAGA), an informal literary group of fantasy authors active from the 1960s to the 1980s, of which Carter was also a member and guiding force, together with a general introduction and introductions to the individual stories by the editor.

All the novelettes were also published as portions of larger works by their respective authors, sometimes in revised form. Vance's "The Bagful of Dreams" became part of his Dying Earth novel Cugel's Saga (1983), while Anderson's "The Tupilak" was incorporated into his novel The Merman's Children (1979). Jakes's "Storm in a Bottle" was included in his Brak the Barbarian collection The Fortunes of Brak (1980). Kurtz's "Swords Against the Marluk" eventually became the basis of part of her Deryni novel The King's Deryni (2014). Moorcock's "The Lands Beyond the World" had already appeared as a section of his Elric novel The Sailor on the Seas of Fate (1976), though its appearance in this anthology did mark its first American publication.
