The 14th World Science Fiction Convention (Worldcon), also known as NyCon II or NEWYORCON, was held on 31 August–3 September 1956 at the Biltmore Hotel in New York City, United States.
The chairman was David A. Kyle.
Attendance was approximately 850.
The primary bid for the 15th World Science Fiction Convention was for London. This would be the first Worldcon outside North America, and there was a small but vocal jingoistic faction of Americans who argued for retaining the Worldcon in North America, claiming "If we let them have it they'll never give it back". Their campaign against the London proposal was opposed by other Americans, most audibly Anthony Boucher, and the London bid won by an ample margin, to loud cheers. There were reportedly petty efforts even after the vote was over to sabotage the London bid, but they failed to hinder it.
It was at this Worldcon that a group of fans (including Bob Tucker, Boyd Raeburn, Dick Eney, Ron Ellik, and Ted White) who had not paid the $7 fee for the convention banquet chose to sit in the balcony and listen to the Guest of Honor speeches. Convention chair Kyle had a messenger tell the "Balcony Insurgents" that Kyle had said they could not sit there. Since almost every fan who wrote about the convention reported the incident, "Dave Kyle Says You Can't Sit Here" became a fannish catchphrase.
