Landmark 81 is a supertall skyscraper in Ho Chi Minh City, Vietnam.^[1] It is primarily invested and developed by Vinhomes, the largest Vietnamese real-estate developer. Landmark 81 holds the position of the tallest building in Vietnam, the second tallest building in Southeast Asia, as well as the seventeenth tallest building in the world overall.^[2][3]

The 461.2-metre (1,513 ft) tall, 81-story building is located at the western banks of the Saigon River in Binh Thanh District, the north side of Ho Chi Minh City's historic center and to the immediate southern side of Saigon Bridge. The tower is built at the heart of Vinhomes Central Park, a $1.5 billion high-end mixed-use urban area. The development comprises hotel and conference facilities, luxury apartments, high-end retail spaces, restaurants, bars, and a multi-story observation deck.

The ground-breaking opening ceremony for the tower was held on 13 December 2014. In October 2017, construction reached floor 69, and with a height of 270 metres (890 ft), surpassing the Bitexco Financial Tower to become the tallest building in Ho Chi Minh City. By January 2018, all floor construction was completed, with only the spire and crown remaining unfinished. On 10 April 2018, the last segment of the crown spire was added, completing Landmark 81.^[4] The building's base, which takes up 6 floors with a total space of 50,000 m² (540,000 sq ft), was opened on 27 July 2018 to mark the 25th anniversary of its owner's parent company, Vingroup.^[5] The observation deck, named Skyview, opened on 28 April 2019.
