Sarah Endacott is a Melbourne-based writer, poet, freelance editor, and publisher whose poetry began appearing in such publications as Hecate, Poetrix, Verandah, and Muse during the 1980s and early 1990s.

Between 1991 and 1998, Endacott was assistant editor and copy-editor for Aurealis: The Australian Magazine of Fantasy and Science Fiction, while also serving as editor for the Australian Science Fiction Writers' News. After she left Aurealis, Endacott launched the speculative fiction magazine Orb at the 1999 Aussiecon Three convention. Since the mid-1990s, her poetry and other writings have also been published in Overland, Ars Poetica, Imago, and The Finishing Post anthology.
