Shea Stadium opened on April 17, 1964 in Flushing Meadows, Queens as the New York Mets played the Pittsburgh Pirates before 48,736 fans. The $25.5 million stadium marked a new beginning for the young club that had played its first two years at the Polo Grounds. The stadium was originally to be called Flushing Meadow Park but was later named for the popular attorney, William A. Shea, who spearheaded the drive to bring National League baseball back to New York following the departure of the Dodgers and Giants in 1957.

The architectural firm of Praeger-Kavanagh-Waterbury designed the stadium to be the first all-purpose facility capable of hosting baseball and football games, seating 55,300 for baseball and 60,000 for the New York Jets football team.
