Peter Anthony Grayson Rawlinson, Baron Rawlinson of Ewell, PC, QC (26 June 1919 – 28 June 2006) was an English barrister, politician and author. He was Conservative Member of Parliament for Epsom for 23 years, from 1955 to 1978, and held the offices of Solicitor General (1962–1964) and Attorney General for England and Wales (1970–1974) and for Northern Ireland (1972–1974). Had he been appointed Lord Chancellor, as seemed likely during the mid-1970s, he would have been the first Roman Catholic to hold that position since Thomas More in 1532.
Rawlinson was born on 26 June 1919, the son of Lieutenant-Colonel A. R. Rawlinson OBE, a figure in military intelligence and a screenwriter.
He was educated by Benedictine monks at Downside, near Bath, and read Law at Christ's College, Cambridge, where he joined the Cambridge Footlights. He was later elected as an Honorary Fellow of his college in 1981. However, he only completed one year at the university, moving on to the Royal Military College, Sandhurst, on the outbreak of the Second World War in 1939. He joined the Irish Guards in 1940, where he remained until he was demobilized as a Major in 1946, having been Mentioned in Despatches in 1943.
