Startide Rising is a 1983 science fiction novel by David Brin and 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.
An early work by the now well-known author David Brin, it was extremely well reviewed when it was published, has remained popular, and served as the seed for three more novels which revolved around the crew of the Earthship Streaker (the Uplift Storm Trilogy). It joins the ranks of double-winners of both the Hugo and Nebula awards for best novel along with classic science fiction novels such as Dune, Neuromancer, Ringworld and Ender's Game. Startide Rising also won the Locus Award for Best Science Fiction Novel in 1984.
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.
