Roslyn Oxley9 Gallery is a contemporary art gallery in Sydney, Australia, owned and operated by Roslyn Oxley and her husband Tony Oxley. The gallery has been a longstanding contributor to international art fairs, and supporter of contemporary art. Artists represented by Roslyn Oxley9 Gallery include Isaac Julien, Yayoi Kusama and many recent representatives for Australia and New Zealand at the Venice Biennale.
The gallery opened in Macdonald Street, Paddington, in March 1982 with an exhibition of paintings by Gareth Sansom. The gallery's second exhibition was part of the Biennale of Sydney, when gallery artist Juan Davila's multi-panel work Stupid as a Painter quickly gained notoriety.
In 1990, the gallery moved to its current location in Soudan Lane, Paddington, opening with an exhibition of paintings by John Nixon. That year the gallery was invited to participate at Art Cologne, the first of many involvements at international art fairs.
In 1993, Jenny Watson became the first Roslyn Oxley9 Gallery artist to represent Australia at the Venice Biennale, with subsequent artists being Bill Henson (1995), Patricia Piccinini (2003), Callum Morton (2007), Hany Armanious (2011) and Fiona Hall (2015). Representing New Zealand have been gallery artists Jacqueline Fraser (2001), Michael Parekowhai (2011) and Bill Culbert (2013). During the 1980s and 1990s, gallery artists were also selected for the Venice Biennale's 'Aperto' section, including Dale Frank (1984), Maria Kozic (1986) and Tracey Moffatt (1997).
