List of megatall skyscrapers in the context of Jeddah Tower

This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least 350 metres (1,150 ft). Such definition excludes non-building structures, such as towers.

The Burj Khalifa (known as the Burj Dubai before its inauguration) is a megatall skyscraper in Dubai, United Arab Emirates. Designed by Skidmore, Owings & Merrill, it is the world's tallest structure, with a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding the antenna, but including a 242.6 m spire) of 828 m (2,717 ft). It has also been the tallest building in the world since its topping out in 2009, surpassing Taipei 101, which had held the record for a half-decade.

Construction of the Burj Khalifa began in 2004; the exterior was completed five years later. The primary structure is reinforced concrete. Some of the structural steel for the building was salvaged from the demolished Palace of the Republic in East Berlin. The building was opened in 2010 as part of a new development called Downtown Dubai. It was designed to be the centerpiece of large-scale, mixed-use development.

According to the Council on Tall Buildings and Urban Habitat (CTBUH), a supertall building is defined as a building between 300 and 599 m (984 and 1,965 ft) in height. Buildings taller than 600 m (1,968 ft) are called "megatall".

As of September 2025, there are 70 cities with at least one supertall or taller building, and 256 completed supertall or taller buildings. Most supertall skyscrapers are located in Asia. The city with the most supertall or taller buildings is Dubai at 33 entries, followed by Shenzhen and New York City with 22 and 18 respectively. China is the country with the most supertall or taller buildings at 138 entries, followed by the United Arab Emirates and the United States with 38 and 34 respectively.

The Shanghai Tower is a 128-story, 632-meter-tall (2,073 ft) megatall skyscraper located in Lujiazui, Pudong, Shanghai. It is currently the tallest building in China and the world's third-tallest building by height to architectural top. It was the tallest and largest LEED-CS Platinum certified building in the world since 2015 to 2024. It was also the second tallest-building in the world, from 2015 to 2021, until the completion of Merdeka 118. The Shanghai Tower also had the world's fastest elevators at a top speed of 20.5 meters per second (74 km/h; 46 mph) until 2017, when it was surpassed by the Guangzhou CTF Finance Center, with its top speed of 21 meters per second (76 km/h; 47 mph).

Designed by the international design firm Gensler and owned by the Shanghai Municipal Government, it is the tallest of the world's first triple-adjacent supertall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. Its tiered construction, designed for high energy efficiency, provides nine separate zones divided between office, retail and leisure use. The US-based Council on Tall Buildings and Urban Habitat cites it as "one of the most sustainably advanced tall buildings in the world."

Merdeka 118, formerly known as Menara Warisan Merdeka, KL 118, and PNB 118, is a 118-storey megatall skyscraper in Kuala Lumpur, Malaysia. At 678.9 m (2,227 ft) tall, it is the second-tallest building and structure in the world, only behind the Burj Khalifa (Dubai, UAE), at 829.8 m (2,722 ft). Construction was controversially entirely funded by Permodalan Nasional Berhad, an investment management company owned by the Malaysian government. The structure was completed in November of 2023, celebrated its grand opening on 10 January 2024, but remains closed and under further construction as of 1 July 2025. The Park Hyatt Kuala Lumpur Hotel, located on level 75, began operation on 7 August 2025.

The building's name, Merdeka, which means "independence" in Malay, is inspired by its proximity to Stadium Merdeka. The spire of the building was completed in December 2022, which marked its final height of 678.9 m (2,227 ft) above ground and 700.9 m (2,300 ft) above sea level.
