Sir William John Peel DSNB DLJ (16 June 1912 – 8 May 2004) was a British Conservative politician who served as Member of Parliament for Leicester South East from 1957 to 1974.

Peel, who was always helpful to Brunei history students, was also a part of a British Parliamentary delegation visiting the Sultanate in 1959.

In the resulting debate, Peel's remarks were denounced by Enoch Powell, who commented: "We cannot, we dare not, in Africa of all places, fall below our highest standards in the acceptance of responsibility".

He was survived by his widow, three daughters (Joanna, Alethea, and Lynda), one son (Quentin), and numerous grandkids and great-grandchildren.

He was the last-surviving former British Resident of Brunei at the time of his death, though not the longest-lived; that honour went to his immediate successor, L. H. N. Davis, who died on 16 June 2003 at the age of 94.
