Ric Throssell (10 May 1922 – 20 April 1999) was an Australian diplomat and author whose writings included novels, plays, film and television scripts, and memoirs. For most of his professional life as a diplomat his career was dogged by unproven allegations that he either leaked classified information to his mother, the writer and communist Katharine Susannah Prichard, or was himself a spy for the Soviet Union.
