Spring Heeled Jack is a character from English folklore said to have existed during the Victorian era and able to jump extraordinarily high. The first claimed sighting of Spring Heeled Jack that is known occurred in 1837. Later alleged sightings were reported all over England, from London up to Sheffield and Liverpool, but they were especially prevalent in suburban London and later in the Midlands and Scotland.

Many theories have been proposed to ascertain the nature and identity of Spring Heeled Jack. The urban legend of Spring Heeled Jack gained immense popularity in its time due to the tales of his bizarre appearance and ability to make extraordinary leaps, to the point where he became the topic of several works of fiction.

Spring Heeled Jack was described by people claiming to have seen him as having a terrifying and frightful appearance, with diabolical physiognomy, clawed hands, and eyes that "resembled red balls of fire". One report claimed that, beneath a black cloak, he wore a helmet and a tight-fitting white garment like an "oilskin". Many stories also mention a "Devil-like" aspect. Spring Heeled Jack was said to be tall and thin, with the appearance of a gentleman, and capable of making great leaps. Several reports mention that he could breathe out blue and white flames and that he wore sharp metallic claws at his fingertips.
The vast urban legend built around Spring Heeled Jack influenced many aspects of Victorian life, especially in contemporary popular culture. For decades, especially in London, his name was equated with bogeymen, as a means of scaring children into behaving by telling them that if they were not good, Spring Heeled Jack would leap up and peer in at them through their bedroom windows, by night.

However, it was in fictional entertainment where the legend of Spring Heeled Jack exerted the most extensive influence, owing to his allegedly extraordinary nature.
