Vashti Bunyan (born Jennifer Vashti Bunyan, 1945, Newcastle, England) is an English singer-songwriter.

Bunyan released her debut album, Just Another Diamond Day in 1970. The album sold very few copies, and Bunyan, discouraged, abandoned her musical career. By 2000, her album had acquired a cult following; it was re-released and Bunyan recorded more songs, initiating the second phase of her musical career after a gap of thirty years.
