Leati "Sika" Anoaʻi is a professional wrestler and a member of the Anoaʻi family. He is best known as a member of Wild Samoans, who wrestled in various promotions including the World Wrestling Federation and Mid-South Wrestling.

Sika teamed with his brother Afa to form the tag team the Wild Samoans. In 1979, they signed with the World Wrestling Federation (now World Wrestling Entertainment). Along with Afa, Sika held the WWF Tag Team Championship on three occasions. They won their first title in the WWF by defeating the team of Ivan Putski and Tito Santana on April 12, 1980. The Wild Samoans held the belts for almost four months before losing them to Bob Backlund and Pedro Morales on August 9. The title was vacated the following day, however, because Backlund already held the WWF Championship and could not defend both titles. A tournament was held to select the new champions, and The Wild Samoans defeated Tony Garea and Rene Goulet to regain the belts.

After losing the title to Garea and Rick Martel, the Wild Samoans left the WWF to compete in Bill Watts' Mid-South Wrestling. They won the tag team championship three times before leaving the promotion to wrestle in the National Wrestling Alliance's Georgia territory.

While there, the Wild Samoans defeated the Fabulous Freebirds to win the NWA National Tag Team Championship. Following their stint in the NWA, the Wild Samoans returned to the WWF. They won their third and final WWF Tag Team Championship on March 8, 1983 by defeating Jules Strongbow and Chief Jay Strongbow.

Sika also headlined the October 3, 1987 edition of Saturday Night's Main Event against Hulk Hogan. In 1988, Anoaʻi also appeared alongside Roddy Piper and other WWF wrestlers in the film Body Slam.

On the March 23, 2007 edition of WWE SmackDown, it was announced that Afa and Sika would be inducted into the WWE Hall of Fame as part of the Class of 2007. On March 31, 2007, the Wild Samoans were inducted into the WWE Hall of Fame by Afa's son, Samu, and Sika's son, Matt.

Sika and Afa also ran The Wild Samoan Training Center, a wrestling school that has produced such alumni as Umaga, Batista, Rikishi, Billy Kidman, and Chris Kanyon.

Sika has two sons, Matthew and Leati Joseph. Matt is a professional wrestler, who appeared in WWE under the name "Rosey" as part of the tage team “Three Minute Warning” and partnering with “Hurricane Helms”.

Leati Joseph, known as Joe, began a wrestling career in 2010, working for WWE under the ring name Roman Reigns, where he is the WWE World Heavyweight Champion in his second reign.
