"Run to the Hills" is a song by the English heavy metal band Iron Maiden. It was released as their sixth single and the first from the band's third studio album, The Number of the Beast (1982). It is their first single with Bruce Dickinson as vocalist. Credited solely to the band's bassist, Steve Harris, Dickinson contributed to the song but could not be credited due to a contractual agreement with his former band Samson. Run to the Hills remains one of the band's most popular songs, with VH1 ranking it No. 27 on their list of the 40 Greatest Metal Songs and No. 14 on their list of the Greatest Hard Rock Songs.

A live version of the song, from Live After Death, was released in 1985 and the original single was reissued in 2002, with all income donated to former drummer Clive Burr's MS Trust Fund. In 1990, as part of The First Ten Years box set, both the original and the 1985 live single were reissued on CD and 12" vinyl, combined with "The Number of the Beast" and "Running Free (live)" respectively.
