"Heatseeker" is a song by Australian hard rock band AC/DC. The song appeared on their 1988 album Blow Up Your Video as the first track. The song was later on Live. The song was also released as a single in various formats, with "Go Zone" as the main B-side. On reaching No.12 in the UK singles chart in 1988, it became their biggest UK chart hit and remained so for 25 years until Highway to Hell reached No.4 in December 2013.

All tracks written by Malcolm Young, Angus Young and Brian Johnson.

In the music video, directed by David Mallet,Angus Young explodes from a life-sized television set. He throws his hat, and it lands on a switch, causing it to flip. An intercontinental ballistic missile is launched, and on the screen is film footage of the Strategic Air Command in the 1950s, 1960s and 1970s. The missile becomes a cruise missile, and travels across the world, whereupon it finally crashes into the Opera House in Sydney, during an AC/DC concert. Angus explodes out of the giant missile's warhead and does a guitar solo. At the end, Angus heads back into the missile's nose cone and leaves.
