Rupert Giles is a fictional character created by Joss Whedon for the television series Buffy the Vampire Slayer. The character is portrayed by Anthony Stewart Head. He serves as Buffy Summers' mentor and surrogate father figure. The character proved popular with viewers, and Head's performance in the role was well received. Following Buffy's run, Whedon intended to launch a television spin-off focused on the character, but rights issues prevented the project from developing. Outside of the television series, the character has appeared substantially in Expanded Universe material such as novels, comic books, and short stories.

Giles' primary role in the series is Watcher to Buffy (Sarah Michelle Gellar) in her capacity as vampire Slayer; he is in the employ of the Watchers' Council, a British organisation that attempts to oversee the actions of the Slayer. From youth, Giles was expected to follow the family tradition and become a Watcher, though as a teenager and young adult he rebelled, dropping out of Oxford University to experiment in dark magic and the rock music scene, until a bereavement brought him to his senses. In adulthood, his loyalty to Buffy and her group of friends costs him his job for a time. As the series progresses, Giles increasingly becomes a father figure to Buffy and her friends Willow (Alyson Hannigan) and Xander (Nicholas Brendon). His encyclopedic knowledge, affinity for magic, moderate fighting skills and willingness to kill when necessary make him an asset to Buffy in her fight against the supernatural evils that plague Sunnydale, California.

Following Buffy's conclusion in 2003, Whedon intended to continue Giles' story as a spin-off series, Ripper, which he intended to produce with the BBC. The series was to depict Giles in ghost stories set in present-day England, coping with loneliness as well as figurative ghosts from his own chequered past. Over several years Whedon restated his commitment to the project, though announced it would take the form of a one-off TV movie. Despite Head's availability and the BBC's willingness to fund the project, rights issues concerning the character ultimately led to it not developing further. Canonically, the character's story is continued in the comic book Buffy the Vampire Slayer Season Eight (2007–2011) and subsequent stories. The Season Eight sequel Angel & Faith (2011–) heavily features Giles and utilizes ideas and characters from the proposed Ripper spin-off.
