Heaven or Las Vegas is the sixth studio album by Scottish alternative rock band Cocteau Twins. It was released on 17 September 1990 by 4AD. It is the band's second major-label release in the US, following Blue Bell Knoll in 1988.

Heaven or Las Vegas peaked at number seven on the UK Albums Chart and number 99 on the US Billboard 200, becoming the band's most commercially successful release. It eventually sold 235,000 copies by 1996, according to Billboard. The album was included in the book 1001 Albums You Must Hear Before You Die, and was voted number 218 in the third edition of Colin Larkin's All Time Top 1000 Albums. In 2020, Rolling Stone listed it at No. 245 in its list of the 500 Greatest Albums of All Time.

The album was voted 18th of Scotland’s 100 Best Rock and Pop Albums in 2003 and was the focus of a BBC Scotland programme, Classic Scottish Albums in 2007. Despite 4AD president Ivo Watts-Russell proclaiming it one of the best-ever releases on his label, he released the group from their contract at the end of 1990 because his relationship with the band had soured.
