"Under Attack" is the last widely released single by Swedish pop group ABBA. It was originally featured as a track on the 1982 compilation album The Singles: The First Ten Years, but was released as a single the following year in most countries. However, in the United Kingdom it was released on 3 December 1982. "Under Attack" was ABBA's 28th single for Polar Music.
A music video for "Under Attack" was filmed on 16 November 1982.
"Under Attack" was not a commercial success upon its release. ABBA's popularity was in decline and the two preceding singles ("Head over Heels" and "The Day Before You Came") had failed to reach No. 1 anywhere.
Despite not being a commercial success, Rolling Stone magazine described the song as "the best thing they've done in three years."
The music video was directed by Kjell Sundvall and Kjell-Åke Andersson.
