Shaquille Rashaun O'Neal, Ed.D. (/ʃəˈkiːl/ shə-KEEL; born March 6, 1972), nicknamed Shaq (/ˈʃæk/ SHAK), is an American retired basketball player, former rapper, actor and current analyst on the television program Inside the NBA. Standing 7 ft 1 in (2.16 m) tall and weighing 325 pounds (147 kg), he was one of the heaviest players ever to play in the NBA. Throughout his 19-year career, O'Neal used his size and strength to overpower opponents for points and rebounds.

Following his career at Louisiana State University, O'Neal was drafted by the Orlando Magic with the first overall pick in the 1992 NBA Draft. He quickly became one of the top centers in the league, winning Rookie of the Year in 1992–93 and later leading his team to the 1995 NBA Finals. After four years with the Magic, O'Neal signed as a free agent with the Los Angeles Lakers. They won three consecutive championships in 2000, 2001, and 2002. Amid tension between O'Neal and Kobe Bryant, O'Neal was traded to the Miami Heat in 2004, and his fourth NBA championship followed in 2006. Midway through the 2007–2008 season he was traded to the Phoenix Suns. After a season-and-a-half with the Suns, O'Neal was traded to the Cleveland Cavaliers in the 2009–10 season. O'Neal played for the Boston Celtics in the 2010–11 season before retiring.
