Bolt is a fictional White German Shepherd Dog and the eponymous protagonist of the 2008 animated feature film Bolt. In the film, he is voiced by John Travolta. His journey and the personal evolution it provokes in him is core to the film's main themes.

In the film, he has spent his entire life from early puppyhood on the set of a television show, kept isolated from the outside world. In the show, Bolt must use his superpowers to save his owner and co-star Penny, whom he loves dearly, from the evil Dr. Calico. However, Bolt believes that he actually has the superpowers possessed by his television character, a delusion the directors of the show maintain by tricking Bolt into thinking his adventures are real, in order to make his performance more authentic.

The character Bolt was created by Chris Williams and Byron Howard together with the chief character designer Joe Moshier. Much of the inspiration for the character was provided by John Lasseter who also oversaw Bolt's visual development. Aside from the film, Bolt also appears in the direct-to-video short film Super Rhino, the two video games Bolt and Disney Infinity, the Sorcerers of the Magic Kingdom trade card role-playing game and has made cameo appearances in Wreck-It Ralph, Tangled and Big Hero 6. Bolt's character received mostly positive critical acclaim from film critics and became breakout-character, leading to strong sales of merchandise and toys following the film's release.
