Startide Rising is a 1983 science fiction novel by American writer David Brin, the second book of six set in his Uplift Universe (preceded by Sundiver and followed by The Uplift War). It earned both Hugo and Nebula Awards for Best Novel. It was revised by the author in 1993 to correct errors and omissions from the original edition. Parts of Startide Rising were published as "The Tides of Kithrup" in the May 1981 issue of Analog. The Tides of Kithrup was an early title of the novel; uncorrected proofs of the novel that still bear that title have become collector's items.
