The Robert J. Collier Trophy is an annual aviation award administered by the U.S. National Aeronautic Association (NAA), presented to those who have made "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year."

The Aero Club of America was a social club formed in 1905 by Charles Jasper Glidden and Augustus Post, among others, to promote aviation in America. It was the parent organization of numerous state chapters, the first being the Aero Club of New England. It thrived until 1923, when it transformed into the National Aeronautic Association, which still exists today. It issued the first pilot's licenses in the United States, and successful completion of its licensing process was required by the United States Army for its pilots until 1914. It sponsored numerous air shows and contests. Cortlandt Field Bishop was president in 1910. Starting in 1911, new president Robert J. Collier began presenting the Collier Trophy.
