The New York-New York Hotel and Casino 9-11 Heroes Tribute Collection consists of materials from the "Heroes of 9-11" display that was at the New York-New York Hotel and Casino in Las Vegas, Nevada from 2001 to 2012. The materials primarily consist of more than 5,000 t-shirts left at the memorial by visitors to Las Vegas, mostly from fire departments and law enforcement agencies from around the United States.

The collection also houses memorabilia and other items left at the memorial, including flags, hats, pins, buttons, flowers, and embroidered emblems and insignias. The materials also contain documentation of the memorial, including promotional and press materials, video recordings from the news media, photographs, and newspaper articles.
