List of tallest buildings in Singapore

Singapore is a highly urbanised country with over 10,000 completed high-rises, the majority of which are located in the Downtown Core, its Central Business District (CBD). In the CBD, there are over 100 skyscrapers. The Guoco Tower currently holds the title of the tallest building in Singapore. It stands at 290 m (950 ft), exempted from the height restriction of 280 m (920 ft) in the CBD. A supertall tower will be built at the current AXA Tower site in the future, standing at 305 m (1,001 ft).
Singapore's history of skyscrapers began with the 1939 completion of the 17-storey Cathay Building. The 70-metre (230 ft) structure was, at the time of its completion, the tallest building in Southeast Asia; it was superseded by the 87-metre (285 ft) Asia Insurance Building in 1954, which remained the tallest in Singapore for more than a decade. Singapore went through a major building boom in the 1970s and 1980s that resulted from the city's rapid industrialisation. During this time OUB Centre (present-day One Raffles Place) became the tallest building in the city-state; the 280 m (919 ft) structure was also the tallest building in the world outside of North America from its 1986 completion until 1989. The skyscraper-building boom continued during the 1990s and 2000s, with 30 skyscrapers at least 140 m (459 ft) tall, many of them residential towers, constructed from 1990 through 2008.
Since 2000, there has been a sharp increase in the number of skyscrapers under construction in the city area, particularly in the Marina Bay district. One project completed in Marina Centre is the Marina Bay Financial Centre, which includes 3 office towers offering 280,000 square metres (3,000,000 sq ft) of office space, 2 residential developments offering 649 apartments and a 16,400-square-metre (176,000 sq ft) retail mall, named Marina Bay Link Mall. There are also several new developments in the city's shopping hub, Orchard Road. The Orchard Residences is a 218 m (715 ft), 52-floor tower built in conjunction with ION Orchard, a shopping centre just beside Orchard MRT station. In addition, the 245 m (804 ft) Ocean Financial Centre, a 43-floor skyscraper, is built in Raffles Place. With the Jurong Lake District envisioned as Singapore's second CBD, more skyscrapers are shaping the skyline there as well. The JTC Summit, a 142 m (466 ft) office tower built in 2000, currently stands as the tallest building outside the Central Region of the country.
A height restriction imposed on Singapore's central business district (CBD) limits buildings to a maximum height of 280 meters unless special permission to build higher is granted. It is in place due to the location of Paya Lebar Air Base. After the base's expected decommissioning in 2030, the restriction will be lifted.
This lists ranks Singapore skyscrapers that stand at least 150 m (492 ft) tall, based on standard height measurement. This includes spires and architectural details but does not include antenna masts. An equal sign (=) following a rank indicates the same height between two or more buildings. The "Year" column indicates the year in which a building was completed.
