Margaret Susan Cheshire, Baroness Ryder of Warsaw and Baroness Cheshire, CMG, OBE (3 July 1924 – 2 November 2000), best known as Sue Ryder, was a British volunteer with Special Operations Executive in the Second World War, who afterwards led many charitable organizations, notably the charity named in her honour.

Margaret Susan Ryder was born in 1924 in Leeds, and educated at Benenden School. When World War II broke out, she volunteered to the First Aid Nursing Yeomanry, even though she was only 15, and she was soon assigned to the Polish section of the Special Operations Executive. In this role, Ryder's job was to drive SOE agents to the airfield where they would take off for their assignments in Europe. In 1943 she was posted to Tunisia and later to Italy.

"I was born on 3 July 1923" - So Sue Ryder begins her autobiography Child of My Love. This was repeated by The Daily Telegraph in her obituary in November 2000, adding that "Lady Ryder of Warsaw, better known as Sue Ryder, has died aged 77", as well as by the BBC and many other news sources.
