Thomas Percy Draper CBE KC (29 December 1864 – 11 July 1946) was an Australian lawyer, politician, and judge.

He was a member of the Legislative Assembly of Western Australia from 1907 to 1911 and again from 1917 to 1921, and was attorney-general in the first government of Sir James Mitchell.

[1] He taught for a term at The High School in Perth, and then spent a period as an associate to Alfred Hensman, a judge on the Supreme Court.

[3] In the 1918 New Year Honours, Draper was made a Member of the Order of the British Empire (MBE) for his wartime services.

During his term in office, he introduced legislation that liberalised Western Australia's divorce laws, and also amended the state's electoral act to allow women to stand for parliament.

[7] The premier at the time, Labor's John Willcock, announced that he would not immediately fill the vacancy left by Draper, due to a perceived lack of need.
