Sir Desmond Henry O'Neil (27 September 1920 – 25 September 1999) was an Australian politician who was a Liberal Party member of the Legislative Assembly of Western Australia from 1959 to 1980.

Early life Born in Perth, to Lillian Frances (née Egan) and Henry McLelland O'Neil, O'Neil went to Aquinas College, and later attended Claremont Teachers College. Enlisting in the Citizen Military Forces and later the Australian Imperial Force, during World War II he saw service in New Guinea, serving with the signal corps of the 3rd Division with the rank of captain.

His old seat of Canning was lost to the Labor candidate, Don May. He had been created a knight bachelor in the 1980 New Year Honours.
