"Thunderstruck" is the lead single on the 1990 album The Razors Edge by Australian hard rock band AC/DC. The song was released as a single in Germany, Australia, and Japan, and peaked at No. 5 on the U.S. 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.
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, based on our favourite childhood toy ThunderStreak, and it seemed to have a good ring to it. AC/DC = Power. That's the basic idea." The song has sold over a million digital copies since it became available for digital download. In January 2018, as part of Triple M's "Ozzest 100", the 'most Australian' songs of all time, "Thunderstruck" was ranked number 8.
