Rainy Day Music is the seventh studio album by American rock band The Jayhawks, released on April 8, 2003. It debuted on the Billboard 200 at number 51, selling 19,000 copies that week.

The Jayhawks are an American alternative country and country rock band that emerged from the Twin Cities music scene in the mid-1980s. Led by vocalists/guitarists/songwriters Gary Louris and Mark Olson, their country rock sound was influential on many bands who played the Twin Cities circuit during the 1980s and 1990s, such as Uncle Tupelo, the Gear Daddies and the Honeydogs. They have released eleven studio albums, with and without Olson, including five on the American Recordings label. After going on hiatus from 2005 to 2009, the 1995 lineup of the band reunited and released the album Mockingbird Time in September 2011; Olson left the band for the second time after the tour to promote the album. After another hiatus in 2013, the 1997 lineup led by Louris reunited to play shows in 2014 to support the reissue of three albums originally released between 1997 and 2003. Since then, the band has continued to tour and record, releasing the albums Live at The Belly Up in 2015; Paging Mr. Proust, co-produced by Peter Buck, in 2016; Back Roads and Abandoned Motels in 2018; and XOXO in 2020.
