Terry Gene Bollea (; born August 11, 1953), better known by his ring name Hulk Hogan, is an American retired professional wrestler. He is signed to WWE as a brand ambassador. Known for his flamboyance and massive physique, and his trademark blond handlebar moustache and bandanas, Hogan is widely regarded as the most recognized wrestling star worldwide, the most popular wrestler of the 1980s and one of the greatest professional wrestlers of all time.

Hogan began his professional wrestling career in 1977, but gained worldwide recognition after signing with the World Wrestling Federation (WWF, now WWE) in December 1983. There, his persona as a heroic all-American helped usher in the 1980s professional wrestling boom, where he headlined eight of the first nine editions of the WWF's flagship annual event WrestleMania (a record which was broken by Roman Reigns). Hogan also was a regular headliner of Saturday Night's Main Event and its spin-off The Main Event in which he headlined 31 editions of both shows combined. During his initial run, he was a five-time WWF Champion, with his 1,474-day reign being the longest of the WrestleMania era ever. He is the first wrestler to win consecutive Royal Rumble matches, winning in 1990 and 1991. His match with André the Giant on WWF The Main Event on February 5, 1988, still holds American television viewership records for wrestling with a 15.2 Nielsen rating and 33 million viewers.

In 1993, Hogan departed the WWF to pursue a career in film and television. He was lured back to the ring when he signed with rival promotion World Championship Wrestling (WCW) in 1994. He won the WCW World Heavyweight Championship six times, and holds the record for the longest reign. In 1996, he underwent a career renaissance upon adopting the villainous persona of "Hollywood" Hulk Hogan, leading the popular New World Order (nWo) stable. As a result, he became a major figure during the "Monday Night War", another boom of mainstream professional wrestling. He headlined WCW's annual flagship event Starrcade three times (1994, 1996 and 1997) in which Starrcade 1997 was the most profitable WCW pay-per-view in the company's history.

Hogan returned to the WWF in 2002 following its acquisition of WCW the prior year, winning the Undisputed WWF Championship for his record equaling (for the time) sixth reign before departing in 2003. He was inducted into the WWE Hall of Fame in 2005, and inducted a second time in 2020 as a member of the nWo. Hogan also performed for the American Wrestling Association (AWA), where he headlined the inaugural AWA closed circuit supercard, Super Sunday in 1983, New Japan Pro-Wrestling (NJPW) – where he was the inaugural winner of the original IWGP Heavyweight Championship – and Total Nonstop Action Wrestling (TNA).

During and after wrestling, Hogan had an extensive acting career, beginning with his 1982 role in Rocky III. He has starred in several films (including No Holds Barred, Suburban Commando and Mr. Nanny) and three television shows (Hogan Knows Best, Thunder in Paradise, and China, IL), as well as in Right Guard commercials and the video game, Hulk Hogan's Main Event. He was the frontman for The Wrestling Boot Band, whose sole record, Hulk Rules, reached No. 12 on the Billboard Top Kid Audio chart in 1995.
