'74 Jailbreak' is the 1984 EP by rockers AC/DC, comprising five hard rock/blues oriented tracks that had previously been released only in Australia. The song "Jailbreak" was also released as a single and a video.

The first track is from the Australian version of 'Dirty Deeds Done Dirt Cheap' (1976), while the rest are from the Australian version of the band's debut album, 'High Voltage,' recorded in 1974 and released early the following year.
