The Locus Award for Best Science Fiction Novel is an annual award presented by Locus, a science fiction and fantasy magazine. The award for Sci-Fi novels was first presented in 1980. However previous to that, from 1971 they award a more generic "Best Novel" award, which coincidentally was only awarded to sci-fi books, so I have also included those books here.
