"Summer Night City" is a song recorded by the Swedish pop group ABBA, written by Benny Andersson and Björn Ulvaeus as a tribute to their hometown of Stockholm. It is the group's second non-album single, released on 6 September 1978. It was recorded during the sessions of the group's upcoming Voulez-Vous album, but was eventually not included. However, it was included on the ABBA compilation album Greatest Hits Vol. 2 in October 1979, more than a year after its release. It was also featured as a bonus track on both the 1997 and 2001 CD re-issues of Voulez-Vous and as the full length version with the original intro on the 2010 re-issue.
