List of tallest buildings in Adelaide

Adelaide contains the vast majority, if not all, the high-rise buildings in the Australian state of South Australia. The city is home to 29 buildings with a height of 75 meters (246 ft) or greater as of 2026, 11 of which are taller than 100 m (328 ft). While it is the largest skyline in South Australia, Adelaide is the most populous city in Australia to not have a single building taller than 150 m (492 ft), the height often used as the definition of a skyscraper.

The tallest building in Adelaide is the 37-storey, 138 m (453 ft) Frome Central Tower One, also called the Adelaidean, a mixed-use residential and hotel building constructed in 2019. Upon completion, it overtook RAA Place, an office high-rise which had been the tallest building in Adelaide since 1988. Adelaide's skyline grew steadily from the 1960s to the early 1990s, which saw the completion of other notable towers commercial such as Telstra House and the Grenfell Centre. Following a pause in high-rise construction in the 1990s and early 2000s, development resumed in the mid-2000s.

Since the mid-2010s, Adelaide has been undergoing an unprecedented high-rise boom, spurred by steady population growth, that has transformed the appearance of its skyline. Eight of Adelaide's ten current tallest buildings were built after 2018, including Frome Central Tower One and the city's second tallest building, The Realm. Adelaide's skyline is set to grow further with the approval of the 160 m (525 ft), 38-storey Festival Tower 2, an office skyscraper with a floor space of around 50,000 square metres (538,000 sq ft). It is expected to be completed no earlier than 2027, and become Adelaide's first skyscraper taller than 150 m (492 ft) if built.

The vast majority of the city's high-rise buildings are located in the central business district, a 4.33 square kilometre (1.67 sq mi) built-up area that is encompassed by the Adelaide Park Lands, separating the skyline from the rest of the city. There are also multiple short residential high-rises in the western sea-side suburb of Glenelg, along the coast of Gulf St Vincent. Height restrictions, which have been enforced since the 1990s, have limited the number of high-rise buildings constructed in the city, although they have been eased in recent times.
