The Exhibition of the Industry of All Nations was a World's Fair held in 1853 in what is now Bryant Park in New York City, in the wake of the highly successful 1851 Great Exhibition in London. It aimed to showcase the new industrial achievements of the world and also to demonstrate the nationalistic pride of a relatively young nation and all that she stood for. Jacob Aaron Westervelt, at that time Mayor of New York, was the President of the exhibition-committee. The general superintendent was Admiral Du Pont.

A world's fair, also known as a universal exhibition or an expo, is a large global exhibition designed to showcase the achievements of nations. These exhibitions vary in character and are held in different parts of the world at a specific site for a period of time, typically between three and six months.
