The Rise of the Synths is a 2019 documentary film written and directed by Iván Castell and narrated by filmmaker and composer John Carpenter. The film explores the origins and growth of the electronic music genre known as synthwave, charting its rise in popularity from the underground online music scene to its recent mainstream exposure, following use in retro-themed soundtracks, notably the 2011 film Drive and more recently, the television series Stranger Things.

Synthwave is an electronic music microgenre that is based predominantly on the music associated with action, science-fiction, and horror film soundtracks of the 1980s. Other influences are drawn from the decade's art and video games. Synthwave musicians often espouse nostalgia for 1980s culture and attempt to capture the era's atmosphere and celebrate it.
