Simon Yorke (24 June 1903 – 7 May 1966) was a Welsh landowner and soldier.
He was born in Erddig, Denbighshire, the eldest son of Philip Yorke (1849-1922), and Louisa Matilda Yorke (née Scott).
He was a lieutenant in the Denbighshire Yeomanry and enlisted as a private in the North Staffordshire Regiment during World War II.
Simon Yorke was found dead in Erddig Park on 7 May 1966, from heart failure.
Unmarried, and without a direct heir, Erddig was inherited by his brother, Philip Scott Yorke, who gifted the estate to the National Trust in 1973.
