The Pious Bird of Good Omen is a compilation album by the British blues rock band Fleetwood Mac, released in 1969.

Wonderful, and two tracks by the blues artist Eddie Boyd with backing by members of Fleetwood Mac.

The closest US equivalent is the English Rose compilation album, released in December 1968 and sharing four songs with Pious Bird.

In 2002, the album was repackaged by Sony BMG as Greatest Hits with cover art very closely resembling the 1971 Greatest Hits album, and with "Shake Your Moneymaker" and "Love That Burns" added to the track listing.

In 2004, when Fleetwood Mac's Blue Horizon era albums were remastered, Pious Bird was reconfigured to remove tracks from the previous two Mac albums and the Boyd tracks, which were replaced by archival recordings from the 1967 and 1968 period.
