Nebula Awards Showcase 2003 is an anthology of science fiction short works edited by Nancy Kress.

The reviewer for Publishers Weekly, while nothing that "it's good to have the Nebula winners for a given year gathered in one place," questions "whether there's enough content here to justify such a book," answering "[o]n balance, ... yes, if only because of the unlikely juxtapositions," and concluding that "[i]n short, the variety of taste shown by the SFFWA continues to be striking and heartening."

The critic feels, however, that "[t]his anthology series is finding a niche for itself by not competing with the two major best-of-the-year collections--Gardner Dozois's mammoth assembly that favors literary experimentation and David Hartwell's relatively compact selection of more traditional SF.

"[2] Roland Green, writing in Booklist, rates the book "[a]s always, an honorable entry among the year’s anthologies.

As the end of his assessment, the journal's young adult reviewer calls the book "a terrific collection for genre fans and YAs new to sf.
