The Naismith Memorial Basketball Hall of Fame is an American history museum and hall of fame, located at 1000 Hall of Fame Avenue in Springfield, Massachusetts. It serves as basketball's most complete library, in addition to promoting and preserving the history of basketball. Dedicated to Canadian-American physician James Naismith, who invented the sport in Springfield, the Hall of Fame inducted its first class in 1959, before opening its first facility on February 17, 1968.

As of 2024^[update], the Hall has formally inducted 436 players, coaches, referees, and other basketball professionals. The Boston Celtics have the most inductees, with 40.

The Naismith Memorial Basketball Hall of Fame was established in 1959, without a physical location, by Lee Williams, a former athletic director at Colby College. In the 1960s, the Hall of Fame struggled to raise enough money to construct its first facility. However, the necessary amount was raised, and the building opened on February 17, 1968, less than a month after the National Basketball Association played its 18th All-Star Game. The Basketball Fame's Board named four inductees in its first year. In addition to honoring those who contributed to basketball, the Hall of Fame sought to make contributions of its own. In 1979, the Hall of Fame sponsored the Tip-Off Classic, a pre-season college basketball exhibition. The Tip-Off Classic has been the start to the college basketball season ever since, and although it does not always take place in Springfield, Massachusetts, generally it returns every few years.

In the 17 years that the original Basketball Hall of Fame operated at Springfield College, it drew over 630,000 visitors. The popularity of the Basketball Hall of Fame necessitated a new facility, and on June 30, 1985, an $11.5 million facility was opened beside the Connecticut River in Springfield. As the new hall opened, it also recognized women for the first time, with inductees such as Senda Berenson Abbott, who first introduced basketball to women at Smith College. During the years following its construction, the Basketball Hall of Fame's second facility drew far more visitors than anticipated, due in large part to the increasing popularity of the game but also to the scenic location beside the river and the second Hall's interesting modern architecture.

In 2002, the Basketball Hall of Fame moved again—albeit merely 100 yards south along Springfield's riverfront—into a $47 million facility designed by Gwathmey Siegel & Associates. The building's architecture features a metallic silver, basketball-shaped sphere flanked by two similarly symmetrical rhombuses. The dome is illuminated at night and features 80,000 square foot (7,400 m²), including a Subway sandwich shop, and an extensive gift shop. The second Basketball Hall of Fame was not torn down, but was converted into an LA Fitness health club. The Basketball Hall of Fame features Center Court, a full-sized basketball court on which visitors can play. Inside the building there are a game gallery, many interactive exhibits, several theaters, and an honor ring of inductees. A large theater for ceremonies seats up to 300. The honorees inducted in 2002, included the Harlem Globetrotters and Magic Johnson, a five-time NBA champion, three-time NBA finals MVP and Olympic gold medalist.

As of 2011, the Basketball Hall of Fame has greatly exceeded attendance expectations, with basketball fans traveling there from all over the world.

In contrast to the Soccer and the National Baseball Halls of Fame, Springfield honors international and American professionals, as well as American and international amateurs, making it arguably the most comprehensive Hall of Fame among major American sports. From 2011 to 2015, seven committees were, and as of 2016, six committees are employed to both screen and elect candidates. Four of the committees screen prospective candidates:

Since 2011, the Veterans and International Committees also vote to directly induct one candidate for each induction class.
