Memorial Collection is a 2009 compilation album of American singer–songwriter and rock and roll pioneer Buddy Holly's master takes and hit singles, including some rare recordings.

Along with Down the Line: Rarities, this album was released to commemorate the 50th anniversary of Holly's death (February 3, 1959).

[7] In an interview with the Lubbock Avalanche-Journal, Holly's eldest brother Larry Holley commented before hearing both this compilation and Down the Line: Rarities, "María [Elena Holly] told me I was definitely going to just break down and cry when I hear all these CDs, because they've cleaned them (the songs) all up and Buddy's music never has come across so pure before.

[2] Robert Christgau, writing for Blender, thinks that the album could easily have fit on to two discs and says that the most interesting songs on the collection were the "undubbed" recordings.

[3] Ed Ward, writing for Paste, complimented Erick Labson's remastering, which he thinks made the recordings clearer than he's ever heard them.
