5748 Davebrin (1991 DX) is a main-belt asteroid discovered on February 19, 1991, by Helin, E. F. at Palomar.

 Elinor "Glo" Helin, the master asteroid hunter of the 1980s and 1990s named this object after American astronomer and science fiction author David Brin.   "Davebrin" is cited as "davidbrin" in some documents.

The asteroid orbits in the inner edge of the Main Belt in a fairly circular trajectory, at a somewhat large inclination of almost 13 degrees.

David Brin persuaded Dr. Helin to name two other newly discovered asteroids after prominent science fiction authors: "poulanderson" after Poul Anderson and "fredpohl" after Frederik Pohl.
