Elysium (also known as 54 Clarke) was a proposed residential skyscraper to be located in the Southbank precinct of Melbourne, Victoria, Australia.

[2] Rising to a height of 243.8 m (800 ft), Elysium would have contained up to 288 residential apartments, across 75 levels; this would have made it one of the tallest buildings in Melbourne.

[1] Its design was notable for a slender appearance – with a width of 12 m (39 ft) at its narrowest – which had earned it a reputation for being one of the "skinniest skyscraper (proposals)" in Melbourne.

[3] First proposed in 2011, Elysium received approval twice in 2013 by then-Planning Minister Matthew Guy; initially in February, 2013, which was later challenged through Victorian Civil and Administrative Tribunal (VCAT),[4][5] and then subsequently in December, 2013.

[6] In 2019, the proposed skyscraper was cancelled, with plans resubmitted for a high-rise residential building of 24 levels.
