The National Baseball Hall of Fame and Museum is an American history museum and hall of fame, located at 25 Main Street in Cooperstown, New York, and operated by private interests. It serves as the central point for the study of the history of baseball in the United States and beyond, displays baseball-related artifacts and exhibits, and honors those who have excelled in playing, managing, and serving the sport. The Hall's motto is "Preserving History, Honoring Excellence, Connecting Generations."

The Hall of Fame was founded in 1939 by Stephen Carlton Clark, the owner of a local hotel. Clark had 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. A new building was constructed, and the Hall of Fame was dedicated on June 12, 1939. (Clark's granddaughter, Jane Forbes Clark, is the current chairman of the Board of Directors.)

Among baseball fans, "Hall of Fame" means not only the museum and facility in Cooperstown, New York, but the pantheon of players, managers, umpires, executives, and pioneers who have been enshrined in the Hall. The first five men elected were Ty Cobb, Babe Ruth, Honus Wagner, Christy Mathewson and Walter Johnson, chosen in 1936; roughly 20 more were selected before the entire group was inducted at the Hall's 1939 opening. As of January 2015, 310 people had been elected to the Hall of Fame.
