Rarities, B-Sides and Slow, Sad Waltzes is an album by the Canadian alt-country band Cowboy Junkies, released in 1999. It was the band's first independent release after the end of their contract with Geffen Records. The album is a compendium of tracks that the band had recorded but not previously released on an album. Two tracks have been released earlier as B-sides on Cowboy Junkies' singles, "If You Gotta Go, Go Now" on "Southern Rain" and "Leaving Normal" on "Anniversary Song". It was released on both True North Records and Latent Recordings in Canada, and on Valley Records in the United States.
