Dafydd ab Hugh (born David Friedman, on October 22, 1960) is a U.S. science fiction author. In the 1980s he served in the United States Navy training to be a Radar Intercept Officer, hoping to be selected to become an astronaut (none of which panned out).

Ab Hugh is most noted for writing fiction in media franchises, including several novels for the Star Trek franchise. He also co-wrote four novels associated with the game Doom with libertarian science fiction author Brad Linaweaver, who currently publishes the occasional magazine Mondo Cult and the Mondo Cult website (without any help from ab Hugh). Ab Hugh has also published unrelated short fiction, though he defies anyone to find any. His most noted story, "The Coon Rolled Down and Ruptured His Larinks, A Squeezed Novel by Mr. Skunk", was nominated for the Hugo Award and Nebula Award.

Ab Hugh is the child of a secular Jewish father and a Welsh-descended mother who converted to Judaism on marriage. He and his wife Sachi currently run an anti-liberal blog, Big Lizards,.
