"Painkiller" is a song by English heavy metal band Judas Priest, released in 1990; it was later released as a single on Columbia Records.

The lyrics tell the story of the Painkiller, the character featured on the cover of the album, who is a cyborg superhero who saves mankind from destruction.

Featuring a thunderous intro by new drummer Scott Travis – a colossal improvement over the technically limited Dave Holland – and highlighted by Halford’s maniacal performance, this was Priest embracing extremity without pandering, and sounding once again vital, relevant, and best of all, more powerful than ever.

[9] Japanese band Babymetal performed an abridged version of the song at the 2016 Alternative Press Music Awards alongside Rob Halford, which led into another Judas Priest song, "Breaking the Law."

Babymetal performed these songs later in the year during their tour supporting Red Hot Chili Peppers, with singer Su-metal performing all vocals and RHCP's Chad Smith playing drums.
