Hits from Yesterday & the Day Before is a greatest hits compilation album by Barenaked Ladies which includes most of the band's US singles released from 1997 to 2010. The album was originally planned to be released on September 13, 2011, then September 20, 2011, but it was finally released on September 27, 2011. The fourteen-track standard edition does not include any new material, although it is the first time "The Big Bang Theory Theme" appears on an album. This is the second greatest hits compilation from Barenaked Ladies, after 2001's Disc One: All Their Greatest Hits (1991–2001).
