The space-opera blockbuster Star Wars franchise has borrowed many real-life scientific and technological concepts in its settings. In turn, Star Wars has depicted, inspired, and influenced several futuristic technologies, some of which are in existence and others under development. In the introduction of the Return of the Jedi novelization, George Lucas wrote: «Star Wars is also very much concerned with the tension between humanity and technology, an issue which, for me, dates back even to my first films. In Jedi, the theme remains the same, as the simplest of natural forces brought down the seemingly invincible weapons of the evil Empire.»

While many of these technologies are in existence and in use today, they are not nearly as complex as seen in Star Wars. Some of these technologies are not considered possible at present. Nevertheless, many of the technologies depicted by Star Wars parallel modern real-life technologies and concepts, though some have significant differences.
