Captain Jack Sparrow is a fictional character from the Pirates of the Caribbean universe who is portrayed by Johnny Depp. He was introduced in the film Pirates of the Caribbean: The Curse of the Black Pearl (2003), and appeared in the back-to-back sequels, Dead Man's Chest (2006) and At World's End (2007). He is also the subject of a children's book series, Pirates of the Caribbean: Jack Sparrow, which chronicles his adolescent years, and the character's image was introduced into the theme park ride that inspired the films when it was revamped in 2006. The character has also appeared in numerous video games.

Sparrow is the Pirate Lord of the Caribbean Sea and can be treacherous, surviving mostly by using wit and negotiation rather than weapons and force; although he will fight if necessary, he tries to flee most dangerous situations. Sparrow is introduced seeking to regain his ship the Black Pearl from his mutinous first mate Hector Barbossa in the first film, and in the sequels, attempts to escape his blood debt to the legendary Davy Jones while battling the East India Trading Co..

Initially, Sparrow was conceived for the first film as a trickster who guides the hero, Will Turner (Orlando Bloom), but Johnny Depp's performance led to Sparrow's role being altered. Depp's flamboyant and eccentric characterization, partially inspired by Pepé Le Pew and Keith Richards, turned Sparrow into an iconic anti-hero and the breakout character of the series. Depp earned his first Academy Award nomination, and in a case of life imitating art, Richards played a cameo role as Sparrow's father in the third film.
