Don't You Know Who I Think I Was? is a greatest hits album by the American rock band The Replacements, released in 2006 by Rhino Records. It includes eighteen tracks spanning the band's eight studio releases from 1981 to 1990, as well as two new tracks recorded specifically for this release. The new tracks—"Message to the Boys" and "Pool & Dive"—feature the three surviving original band members: singer and guitarist Paul Westerberg, bass guitarist Tommy Stinson, and drummer Chris Mars. However, Mars does not play drums on these tracks: they were played by session drummer Josh Freese while Mars sang backing vocals.
