Macy's, Inc. is an American holding company of department stores. Upon its establishment in 1929, Federated held ownership of the regional department store chains Abraham & Straus, Lazarus, Filene's, and Shillito's. Bloomingdale's joined Federated Department Stores the next year. Throughout its early history, frequent acquisitions and divestitures saw the company operate a number of nameplates. In 1994, Federated took over the department store chain Macy's. Despite a long history of preserving regional nameplates, with the acquisition of The May Department Stores Company in 2005, they were retired and replaced by the Macy's and Bloomingdale's brands nationwide by 2006. Ultimately, Federated itself was renamed Macy's, Inc. in 2007.

Macy's Herald Square is the flagship of Macy's department store, as well as the Macy's, Inc. corporate headquarters, on Herald Square in Manhattan, New York City. The building's 2.5 million square feet (230,000 m2), which includes 1.25 million square feet (116,000 m2) of retail space, makes it the largest department store in the United States and among the largest in the world.
