The William C. Morris YA Debut Award is an annual award given to a work of young adult literature by a "first-time author writing for teens".
 It is administered by the Young Adult Library Services Association (YALSA), a division of the American Library Association (ALA).
 It was named for twentieth-century American publisher William C. Morris (born 1928 or 1929 and raised up in Eagle Pass, Texas, died Sept 28, 2003 in Manhattan), whom YALSA calls an innovator and "an influential innovator in the publishing world and an advocate for marketing books for children and young adults".
 The award is funded by the William C. Morris Endowment, established in 2000 and activated in 2003 with a bequest of $400,000 from the Morris estate.
