Sir Peter Geoffrey Roberts, 3rd Baronet (23 June 1912 – 22 July 1985) was a British Conservative Party politician. He was elected at the 1945 general election as member of parliament (MP) for Sheffield Ecclesall. When that constituency was abolished for the 1950 general election, he was elected for the newly created Sheffield Heeley constituency. He retired from Parliament at the 1966 election, when the seat was taken by Labour candidate Frank Hooley. Sir Peter married Judith Hempson in 1939: they had a son and four daughters. Sir Peter was succeeded as Baronet by his son Samuel, married to Georgina Cory since 1977. Lady Roberts and Sir Samuel run the Cockley Cley Estate near Swaffham. Lady Roberts became the first woman Chairman of the Norfolk Country Landowners Association. He was Sheriff of Hallamshire in 1970.
