Supreme Court Gardens is a park in the central business district of Perth, Western Australia, bounded by Riverside Drive, Barrack Street, Governors Avenue, and the buildings of the Supreme Court of Western Australia.

In the late 1880s Perth Water extended further north than its current boundary, and the river covered part of the area now occupied by the Supreme Court Gardens.

[3] The gardens have had extensive trees, shrubbery and fencing, various small structures at different stages in the grounds in the past.

[5] By the 2000s large amounts of low shrubs and fences had been removed and better lighting introduced.

The gardens have had a significant number of events and concerts,[8][9][10] many associated with the Perth International Arts Festival.
