The Mascot Hall of Fame, formally "The Mascot Hall of Fame Interactive Children's Museum", is a hall of fame for North American sports mascots. It was founded by David Raymond, who was the original Phillie Phanatic from 1978 to 1993. It was founded as an online-only hall, with an induction ceremony taking place each year in Philadelphia, Pennsylvania. However, in September 2014, Raymond's mascot company signed a memorandum of understanding with the City of Whiting, Indiana, to develop a permanent Mascot Hall of Fame on the south shore of Lake Michigan. The museum opened December 26, 2018.
