Best of Dark Horse 1976–1989

Best of Dark Horse 1976–1989 is a compilation album by British musician George Harrison, released in October 1989. His second compilation, after the Capitol/EMI collection The Best of George Harrison (1976), it contains songs from Harrison's releases on his Dark Horse record label between 1976 and 1987. The album also includes a 1989 single, "Cheer Down", which was Harrison's contribution to the soundtrack of the film Lethal Weapon 2, and two tracks recorded specifically for the collection: "Poor Little Girl" and "Cockamamie Business". Despite the popularity of Harrison's work over this period – both as a solo artist with his Cloud Nine album (1987), and as a member of the Traveling Wilburys – the compilation failed to achieve commercial success.

Best of Dark Horse became out of print in the early 1990s, and it remained unavailable when Harrison's Dark Horse catalogue was reissued in 2004. It remains the only official release to include "Poor Little Girl" and "Cockamamie Business".
