Artspace Sydney, Contemporary art gallery in Woolloomooloo, Australia.

Artspace Sydney is a non-collecting contemporary art centre in the heritage-listed Gunnery Building in Woolloomooloo, fronting Sydney Harbour. It reopened in December 2023 after a transformation that moved the entrance from Cowper Wharf Road to Forbes Street Plaza and restored all three floors. The ground floor holds expanded galleries, while the first floor houses education, outreach, digital broadcast, performance and production spaces.

Artspace was founded in 1983 as an artist-run gallery in a former hat factory at 11 Randle Street, Surry Hills, opening with the exhibition A Different Perspective curated by Terence Maloon. In 1992 it moved to The Gunnery in Woolloomooloo, a heritage-listed building erected as a bulk store for the Sydney Morning Herald and used for defence purposes until 1948. Artists had squatted and exhibited there in the 1970s and 1980s, and in 1989 their protest against a proposed sale kept the building standing. After a redevelopment begun in 2021, Artspace reopened in December 2023.

Artspace runs rent-free One Year Studio residencies for artists at any career stage, alongside the Ideas Platform and the Volume book fair. Its 1984 show Koori Art 84 was the first exhibition devoted to emerging Aboriginal artists, mostly from an urban context, and featured Banduk Marika, Fiona Foley, Lin Onus and Michael Riley.

The entrance moved from Cowper Wharf Road to Forbes Street Plaza during the redevelopment, and all three floors were restored with universal access throughout. The building fronts Sydney Harbour in Woolloomooloo, within reach of the East Sydney precinct. The ground floor holds the expanded galleries, while the first floor houses education, outreach, digital broadcast, performance and production spaces.

The Gunnery was built at the turn of the 20th century as a bulk store for the Sydney Morning Herald, then used by the Commonwealth Government for defence purposes until decommissioning in 1948. In the 1970s and early 1980s artists squatted here, using it for studios, performances and exhibitions. In 1989 artists successfully protested a proposed sale for redevelopment at the Land & Environment Court, preventing demolition.
