The Railway Exchange Building is a 84.4 m (277 ft), 21-story high-rise office building in St. Louis, Missouri. The 1914 steel-frame building is in the Chicago school architectural style, and was designed by architect Mauran, Russell & Crowell. The building was the city's tallest when it opened, and remains the second-largest building in downtown St. Louis by interior area, with almost 1,200,000 square feet (110,000 m²) of space.

The building was long home to the flagship store of the Famous-Barr chain of department stores — and the headquarters of its parent company May Department Stores — until the brand was bought by Macy's; the store was converted to a Macy's in 2006. Macy's decided to sell the building in 2008 and finally closed the store in 2013.

In January 2017, real estate group Hudson Holdings of Delray Beach, Florida, purchased the building for over $20 million.
