Artis Gilmore Sr. (born September 21, 1949) is an American former professional basketball player who played in the American Basketball Association (ABA) and National Basketball Association (NBA). Gilmore was inducted into the Naismith Memorial Basketball Hall of Fame on August 12, 2011.
A star center in his two years of college basketball at Jacksonville University, Gilmore led the Dolphins to the NCAA Division I championship game in 1970, where his team was beaten 80–69 by the UCLA Bruins. Gilmore remains the top player in rebounds per game in Division I history.
Gilmore followed five All-Star seasons with the Kentucky Colonels of the ABA by becoming the first overall pick in the 1976 ABA Dispersal draft, which dispersed the players in the ABA clubs, such as the Colonels, that did not join the NBA. During his career, Gilmore was an 11-time All-Star, the ABA Rookie of the Year, and an ABA Most Valuable Player (MVP). Nicknamed "The A-Train", the 7-foot-2-inch (2.18 m) Gilmore once played in 670 consecutive games.
