Blood on the Slacks is the fourth full-length album by the American band Golden Smog. It was released by Lost Highway Records on April 24, 2007, less than a year after their previous album, Another Fine Day. The album's name is a play on Bob Dylan's 1975 album "Blood On The Tracks". It was the first release from the group to not feature the Wilco frontman Jeff Tweedy as part of the lineup since 1995's Down by the Old Mainstream.
