James Reiher Snuka (born James Wiley Smith; May 18, 1943 – January 15, 2017) was a Fijian and American professional wrestler, better known by the ring name Jimmy "Superfly" Snuka.

Snuka wrestled for several promotions from the 1970s to 2010s. He was best known for his time in the World Wrestling Federation (WWF, now WWE) in the 1980s to where he was credited with introducing the high-flying wrestling style. He was inducted into the WWF Hall of Fame in 1996, and was the inaugural ECW World Heavyweight Champion (a title he held twice) in Eastern Championship Wrestling (later Extreme Championship Wrestling). His children, Sim Snuka and Tamina Snuka, are both professional wrestlers.

Snuka was indicted and arrested in September 2015 on third-degree murder and involuntary manslaughter charges in relation to the May 1983 death of his girlfriend and mistress, Nancy Argentino, in Allentown, Pennsylvania. He pleaded not guilty, but was found unfit to stand trial in June 2016 due to dementia. Terminally ill with stomach cancer, his charges were dismissed on January 3, 2017, twelve days before his death.

Snuka was born in the British colony of Fiji on May 18, 1943, to Louisa Smith and Charles Thomas. Thomas was married to another woman, and Smith was engaged to Bernard Reiher. Before Snuka was born, his mother married Reiher. As a child, Snuka moved with his family to the Marshall Islands and then to Hawaii.

Snuka was active in amateur bodybuilding in Hawaii in the 1960s. He also enjoyed some success as a professional bodybuilder, earning the titles of Mr. Hawaii, Mr. Waikiki and Mr. North Shore.

Snuka opted to go into the more lucrative career of professional wrestling due to the uncertainty of his making a living in bodybuilding. While working at Dean Ho's gym in Hawaii, Snuka met many of the wrestlers who worked in the South Pacific region and decided to try the business. Snuka made his debut as Jimmy Kealoha fighting Maxwell "Bunny" Butler in Hawaii in 1970. He later moved to the mainland and wrestled for Don Owen’s NWA Pacific Northwest territory where he held the belt as heavyweight champion six times. He first won the title by pinning Bull Ramos on November 16, 1973. It was in this territory that Reiher transformed himself into Jimmy Snuka. Snuka also held the NWA Pacific Northwest Tag Team Championship six times with partner Dutch Savage. Snuka also had a two-year feud with another rookie, Jesse "the Body" Ventura.

Snuka also wrestled in several other National Wrestling Alliance (NWA) regions, including Texas. In 1977, he won both the Texas heavyweight and tag team titles. Snuka then left for the Mid-Atlantic where he formed a tag team with Paul Orndorff. In their first television match they defeated the NWA World Tag Team champions Jack and Jerry Brisco in a non-title bout. Orndorff and Snuka defeated Baron von Raschke and Greg Valentine to become the tag team title holders in 1979. On September 1, 1979, Snuka defeated Ricky Steamboat to hold the United States title. Snuka also formed a tag team with Ray Stevens while with this promotion. His career eventually led him to Georgia, where he teamed with Terry Gordy to win the NWA National Tag Team Championship by defeating Ted DiBiase and Steve Olsonoski."

In January 1982, Snuka entered the World Wrestling Federation (WWF) as a villainous character under the guidance of Captain Lou Albano. Snuka lost several title shots at WWF champion Bob Backlund, including a steel cage match at Madison Square Garden on June 28, 1982, in which Snuka leapt from the top of the cage and missed a prone Backlund, who managed to roll out of the way and escape the cage for the win. The contest was declared Match of the Year by Pro Wrestling Illustrated.
