Stephanie McMahon Levesque (born Stephanie Marie McMahon; September 24, 1976)is an American businesswoman and professional wrestling personality. She is the chief brand officer (CBO) of WWE and appears as an on-screen authority figure and occasional wrestler on both the Raw and SmackDown brands.

She is a fourth generation wrestling promoter as a member of the McMahon family, she has worked for WWE since she was a young girl (modeling T-shirts and other merchandise for various WWE catalogs) working her way up to receptionist, then in various front office jobs up to and including her current CBO position. She is the great-granddaughter of Roderick "Jess" McMahon, granddaughter of Vincent J. McMahon, daughter of WWE Chairman and CEO Vincent K. McMahon and retired WWE CEO and former Administrator of the Small Business Administration Linda McMahon, the younger sister of WWE part-owner/wrestler Shane McMahon, and wife of WWE executive/wrestler Paul "Triple H" Levesque.

McMahon began appearing regularly on-air for WWE (then WWF as the World Wrestling Federation) in 1999 as a part of a storyline with The Undertaker. After a brief on-screen relationship with Test, she was engaged to Triple H—whom she married both on-screen and later in real life—which resulted in The McMahon-Helmsley Faction storyline. She has held the WWF Women's Championship once. In 2001, she was the on-screen owner of Extreme Championship Wrestling during The Invasion. The following year, she was the SmackDown General Manager, but stopped appearing regularly on television after an "I Quit" match with her father Vince McMahon.

After making only sporadic appearances for several years, McMahon began appearing regularly on Raw in 2008 as the Raw brand general manager before disappearing once again. By mid-2013, McMahon returned to regular on-air appearances in the WWE, this time under the gimmick of an unctuous, judgmental, bullying owner along with on-screen chief operating officer, her husband, Triple H. From 2013 to 2016, they acted as a power couple known as The Authority, making what were often shady decrees while claiming only to be concerned for "what's best for business," all the while romanticizing each other in the process with public displays of affection. The Authority would later expand into a stable, with its co-leaders being Triple H and herself.
