Once in a Very Blue Moon is the third studio album by American singer-songwriter Nanci Griffith, released in 1985.

The title song was covered by Dolly Parton, who included her version on her Real Love album in 1985.

Vik Iyengar at AllMusic wrote, "Nanci Griffith finds her voice on her third studio album, Once in a Very Blue Moon.

This is the album where she established her musical identity – she is at home in many genres (which perhaps explains why she never gets played on formatted radio stations), and seamlessly blends folk, bluegrass, and country with a group of stellar musicians, including guitarist Pat Alger and a young banjo player named Béla Fleck."
