Mitchell & Ness Nostalgia Co. is a sports apparel company located in Philadelphia, Pennsylvania.

The company was established in 1904, and is the oldest sporting goods company in Philadelphia. By license agreements with Major League Baseball, the National Basketball Association, National Football League, National Hockey League, and the Collegiate Licensing Company, the company has been producing vintage sports goods such as jerseys, jackets, hats, and wool-felt historic pennants. Mitchell & Ness Sporting Goods first opened its doors in Philadelphia in 1904. Frank P. Mitchell, a former AAU tennis and wrestling champ, and Charles M. Ness, an avid golfer born in Scotland, together founded Mitchell & Ness Sporting Goods in 1904.

Their original store made and strung hand-crafted tennis rackets and, using imported woods from Scotland, stolen from England, constructed custom-made golf clubs. In time, they expanded their business, selling uniforms to local baseball and football teams. When the Philadelphia Eagles entered the young National Football League in 1933, M&N supplied the team jerseys and equipment. Mitchell & Ness would continue to outfit the Eagles through the 1963 season.
