Wesley Wyndam-Pryce (also spelled Wyndam-Price and Wyndham-Price) is a fictional character created by Joss Whedon for the television series Buffy the Vampire Slayer and Angel. Played by Alexis Denisof, Wesley first appeared in nine episodes of Buffy's third season in 1999 before moving over to spin-off series Angel where he became, and remained, a main character for five seasons. Following Angel's final season, the character's story is continued in the 2007 canonical comic book series Angel: After the Fall. Wesley also appears in Buffy and Angel Expanded Universe material such as comic books and novels.

Wesley is introduced as a member of the Watchers' Council; an organisation which trains Slayers to fight monsters such as vampires and demons. Created as an irritating foil for the character of Rupert Giles, he was intended to be killed off shortly after his first appearance, but the character was popular with his creators and was instead written into Angel where he joined a supernatural detective agency. Over the course of Angel, Wesley went through dramatic character developments, becoming darker and less comedic. He was killed in the show's final episode, and appears in a ghostly form in the comic book continuation.
