Jacqueline Louise Fuchs is an American former musician. Under her stage name Jackie Fox, she played bass guitar for the pioneering all-girl teenage rock band The Runaways. She is the sister of screenwriter Carol Fuchs and sister-in-law of Castle Rock Entertainment co-founder Martin Shafer.

The Runaways were an American all-female rock band who recorded and performed from 1975 to 1979. Formed in 1975 in Los Angeles, the band released four studio albums and one live album during its run. Among their best-known songs are "Cherry Bomb", "Hollywood", "Queens of Noise" and a cover version of the Velvet Underground's "Rock & Roll". Never a major success in the United States, the Runaways became a sensation overseas, especially in Japan, thanks to the single "Cherry Bomb".
