Morphettville Racecourse is the main horse racing course for the Australian state of South Australia, incorporating two separate tracks.

After five or six years of existence in name only, the SAJC acquired, thanks to the generosity of Sir Thomas Elder, its own freehold property at Morphettville ("The Bay of Biscay Course") and held its first meeting there on 3 January 1876.

The Morphettville Racecourse Wetland was a joint initiative of the Patawalonga Catchment Water Management Board and the South Australian Jockey Club.

[3] The wetland covers an area of 3.5 hectares (8.6 acres) in the middle of the racecourse on the corner of Anzac Highway and Morphett Road.

[3] The catchment area for the wetland includes stormwater flow from two drains in Bray Street, south of the racecourse.

Water enters a sediment pond where floating litter is collected in a net and large materials settle out.
