The SA Fillies Classic is a Group 3 race for three-year-old fillies conducted by the South Australian Jockey Club at Morphettville in Adelaide.

The SA Fillies Classic is run under set weights conditions over 2500m and is registered as the South Australian Oaks. It was run as the SA Oaks from 1951 until 2008.

The race was first run in 1951 over 10 1/2 furlongs (2100m) and remained at that distance until 1960. From 1961-1984 the distance was 10 furlongs (2000m) but was extended to 2400m in 1986 when the South Australian Jockey Club introduced the Australasian Oaks over 2000m.

The SA Fillies Classic was run over 2400m from 1986-1994 and went to 2500m in 1995.

From 1951 until 1984 the SA Oaks/Fillies Classic was run in the spring. It was not held in 1985 to permit a change to an autumn date.

The race is traditionally held at Morphettville but was run at Cheltenham Park in 1979 and at Victoria Park in 1980.

The SA Oaks/Fillies Classic was a Group 1 race from 1980-2004, Group 2 in 2005 and 2006 and has been Group 3 since 2007.
