Fashion Outlets of Niagara Falls, formerly Niagara Factory Outlet Mall, Niagara Factory Outlets, and Prime Outlets of Niagara Falls, is an outlet mall serving Niagara Falls, New York. The outlet mall opened in 1982 in a former King's discount store.
A 1995 expansion added sixty stores, including a Saks Fifth Avenue outlet store called Off Fifth. In 1997, the mall was acquired by Prime Retail (now part of The Lightstone Group) for $89 million. A $12 million renovation in 2006 added new tenants and renamed the complex Fashion Outlets Niagara Falls USA. The mall became a Macerich property in 2011.
