An Australian Son (1996) is a memoir by former Australian diplomat, Gordon Matthews (b. 1952).

Gordon Matthews was adopted at birth into a white middle-class family. That he had dark skin was a source of confusion about his identity until it was suggested that he apply for a Commonwealth Aboriginal grant at university.

From then, Matthews identified as Aboriginal Australian, until he found out his father was a Sri Lakan man who had married Matthews' mother and gone on to have another three children.
