Just Another Diamond Day is the debut album of English singer-songwriter Vashti Bunyan.
In the mid to late 1960s, Bunyan was under contract to Andrew Oldham, which saw her release two singles. However, Bunyan found the experience frustrating, and decided to head for the Scottish islands in search of an artistic commune supposedly established by Donovan. She travelled around the countryside with her partner Robert in a horse-drawn wagon. It was during these travels that she wrote the songs which would later appear on Just Another Diamond Day. .
