"Rush" is a song by English band Big Audio Dynamite II from their fifth album, The Globe (1991). A longer version of "Rush", entitled "Change of Atmosphere", had previously appeared on the group's 1990 album Kool-Aid.

The song samples several musical recordings, including the keyboard component of the Who's song "Baba O'Riley", the organ from the introduction to the Deep Purple song "Child in Time", a drum break from Tommy Roe's "Sweet Pea", drums and guitars from a break in Pigmeat Markham's "Here Comes the Judge", a line from the Sugarhill Gang's song "Rapper's Delight" where Big Bank Hank raps "a time to cry, a time to laugh", and a vocal sample from "You Keep Me Swingin'", from Peter Sellers' Songs for Swingin' Sellers. The shorter 7-inch version omits all the samples except for the "Baba O'Riley" keyboard and the "Sweet Pea" drums.

"Rush" was a number-one hit on the US Billboard Modern Rock Tracks chart for four weeks in 1991, becoming the chart's most successful hit of 1991, and it also topped the Australian and New Zealand singles charts. In the United Kingdom, "Rush" was originally released as the B-side to the 1991 re-release of the Clash's "Should I Stay or Should I Go". The A-side was immensely popular due to its inclusion in a Levi Strauss & Co. advert, causing it to climb to number one on the UK Singles Chart. The sleeve art for the 7-inch and CD singles displayed the Clash on the front, and BAD II on the rear. The record label displays "Should I Stay or Should I Go" as side "A" and "Rush" as side "AA", making it effectively a double A-side release.
