The National Baseball Hall of Fame and Museum is a history museum and hall of fame in Cooperstown, New York, operated by private interests. It serves as the central point of the history of baseball in the United States and displays baseball-related artifacts and exhibits, honoring those who have excelled in playing, managing, and serving the sport. The Hall's motto is "Preserving History, Honoring Excellence, Connecting Generations". Cooperstown is often used as shorthand (or a metonym) for the National Baseball Hall of Fame and Museum, similar to "Canton" for the Pro Football Hall of Fame in Canton, Ohio.

The Hall of Fame was established in 1939 by Stephen Carlton Clark, an heir to the Singer Sewing Machine fortune. Clark sought to bring tourists to a city hurt by the Great Depression, which reduced the local tourist trade, and Prohibition, which devastated the local hops industry. Clark constructed the Hall of Fame's building, and it was dedicated on June 12, 1939. (His granddaughter, Jane Forbes Clark, is the current chairman of the board of directors.) The erroneous claim that Civil War hero Abner Doubleday invented baseball in Cooperstown was instrumental in the early marketing of the Hall.

An expanded library and research facility opened in 1994. Dale Petroskey became the organization's president in 1999. In 2002, the Hall launched Baseball as America, a traveling exhibit that toured ten American museums over six years. The Hall of Fame has since also sponsored educational programming on the Internet to bring the Hall of Fame to schoolchildren who might not visit. The Hall and Museum completed a series of renovations in spring 2005. The Hall of Fame also presents an annual exhibit at FanFest at the Major League Baseball All-Star Game.

The San Francisco Giants have the most inductees, with 66.
