Trilogy is the third studio album by guitarist Yngwie Malmsteen, released in October 1986 through Polydor Records.

In the liner notes, Malmsteen dedicates the album to the memory of the late Swedish Prime Minister Olof Palme, who was assassinated on 28 February 1986.

Steve Huey at AllMusic gave Trilogy four stars out of five, calling it Malmsteen's second best album after his 1984 debut Rising Force.

Malmsteen's compositional and lyrical skills were described as being at their peak on Trilogy, while his guitar work was praised as "jaw-droppingly fast and technically demanding".

Huey listed "Dark Ages", "You Don't Remember, I'll Never Forget" and "Trilogy Suite Op: 5" as highlights.
