MahaNakhonis a mixed-use skyscraper in the Silom/Sathon central business district of Bangkok, Thailand. It opened in December 2016. It features the unconventional appearance of a glass curtain walled square tower with a cuboid-surfaced spiral cut into the side of the building. Following transfer of the first residential units in April 2016, at 314.2 metres (1,031 ft) with 77 floors, it was recognized as the tallest building in Thailand on 4 May 2016 by the Council on Tall Buildings and Urban Habitat (CTBUH). Featuring hotel, retail and residences, 200 units of The Ritz-Carlton Residences, Bangkok inside the building are priced between around US2,100,000 to US$17,000,000, making it one of the most expensive condominiums in Bangkok.

In September 2014, Ritz-Carlton Residences, Bangkok at MahaNakhon, was named "Best Luxury Condo Development 2014 (Bangkok)" at the Thailand Property Awards. In October 2014, The Ritz-Carlton Residences, Bangkok at MahaNakhon was named "Best Thailand Development 2014" and "Best Luxury Condominium Southeast Asia 2014" at the SE Asia Property Awards.

Subsequently the project has also been recognised with presentations at CTBUH, the Council for Tall Buildings and Urban Habitat and Chulalongkorn University.
