Colony Square is a mixed-use development and sub-district in Midtown Atlanta, Georgia, located on Peachtree Street in between 14th and 15th Streets. The oldest high-rise development in Midtown, the sub-district was built between 1969 and 1975, with Henri Jova of Jova/Daniels/Busby serving as principal architect. It was the first mixed-use development in the Southeast.
Designed in modernist style, Colony Square comprises three skyscrapers, two containing offices (Colony Square 100 and Colony Square 400) and one housing a hotel, the W Atlanta-Midtown. The three skyscrapers are connected by Colony Square Mall, located beneath a sky-lit atrium and offering a food court, retail, and an athletic club. Also within the sub-district are three mid-rise condominium buildings (two comprise Colony House and the third, Hanover House). Colony Square also contains street-level restaurants, including 5Church Atlanta, Establishment, Chick-fil-a and Starbucks. 
North American Properties agreed to terms with Tishman Speyer to purchase the property for $164.5 million in Q4 2015. The deal will include the retail and office space, but not the condominiums and hotel that are part of the complex. North American Properties has major renovation plans for the retail component. The new owner plans to reconfigure the shop space in order to allow shoppers to stroll freely through a courtyard that faces the main street. These plans are scheduled to be completed by July 2018.

In 1995 the Consulate-General of Japan in Atlanta was located in Colony Square. In 2002 the consulate announced it was moving from Colony Square to One Alliance Center. The consulate had over three years left in the lease of Colony Square. Because TrizecHahn Office Properties Inc. owned both office properties, the consulate was easily able to move to its new location.
