WWE is a professional wrestling promotion based in Stamford, Connecticut. Employees in WWE consist of professional wrestlers, managers, play-by-play and color commentators, ring announcers, interviewers, referees, trainers, producers, script writers and various other positions. Executives and board of directors are also listed.

WWE employees' contracts range from developmental contracts to multi-year deals and they appear as independent contractors. Employees on the main roster appear on specific brands (Raw and SmackDown) for WWE television programming, pay-per-view and at live events, and anyone from the main roster can appear on NXT and Superstars. Developmental employees appear at Florida Championship Wrestling (FCW).

Employees and management are organized by role within the promotion. The ring name of the employee is written on the left, while the employee's real name is on the right. If a wrestler is inactive for any reason, due to injury, suspension, not wrestling in 30 days or otherwise, that information is noted.

Mark William Calaway (born March 24, 1965) is an American professional wrestler better known by his ring name The Undertaker. He is signed to WWE and is the company's most tenured competitor. Calaway began his wrestling career with World Class Championship Wrestling (WCCW) in 1984. He joined World Championship Wrestling (WCW) as "Mean" Mark Callous in 1989. When WCW did not renew Calaway's contract in 1990, he signed with the World Wrestling Federation in October and, after shortening his name from Kane the Undertaker to simply The Undertaker, has remained with the company since.

The Undertaker has two contrasting personas. The first is the role of The Deadman, an undead, occult-like figure, which has consisted of many different styles. He debuted his original Deadman persona during his own on-camera debut at Survivor Series (1990). At this event, the Undertaker was clad as a Western mortician. Next, in October of 1998, the Undertaker appeared as the leader of the Ministry of Darkness (with similar apparel). Since WrestleMania XX, the Undertaker has appeared as a hybrid version of the Deadman character, using elements of the previous Deadman incarnations.
