"Thunderstruck" is the lead single on the 1990 album The Razors Edge by the hard rock group AC/DC. The song was released as a single in Germany, Australia, and Japan, and peaked at No. 5 on U.S. the Billboard Hot Mainstream Rock Tracks. In 2010, "Thunderstruck" topped Triple M's Ultimate 500 Rock Countdown in Melbourne, Australia. The top five were all AC/DC songs. This is one of the only two songs released after "For Those About to Rock (We Salute You)" that the band still performs live in concert, the other being "Rock N Roll Train".
Angus Young stated in the liner notes of the 2003 re-release of The Razors Edge:
"It started off from a little trick I had on guitar. I played it to Mal and he said 'Oh, I've got a good rhythm idea that will sit well in the back.' We built the song up from that. We fiddled about with it for a few months before everything fell into place. Lyrically, it was really just a case of finding a good title ... We came up with this thunder thing and it seemed to have a good ring to it. AC/DC = Power. That's the basic idea."
The video which accompanied the single was filmed at London's Brixton Academy on 17 August 1990. The audience members were given free T-shirts with the words 'AC/DC – I was Thunderstruck' on the front and the date on the back, and these T-shirts were worn by the entire audience throughout the filming of the video.
The song has sold over a million digital copies since it became available for digital download.
