Nightbird is a 2-CD plus 1-DVD live album by American singer Eva Cassidy, released posthumously in November 2015, nineteen years after her death.

Matt Adams of The Herts Advertiser wrote: "An exceptional release, offering fresh insights into perhaps one of the greatest female vocalists of all time.

"[3] Michael Bailey of All About Jazz said: "Nightbird reveals a modern song stylist not unlike Frank Sinatra.

She was equally at home with the Box Tops ("The Letter") and Bobby Troup ("Route 66"); Peggy Lee ("Fever") and Aretha Franklin ("Chain of Fools").

Nightbird is a singular event to be savored and a talent too great to have experienced for such a short time.
