Peter Leonard Brooke, Baron Brooke of Sutton Mandeville, CH, PC (born March 3, 1934), is a British politician, a former Conservative Cabinet member, and former Member of Parliament for the Cities of London and Westminster.

He is the son of Henry Brooke, Baron Brooke of Cumnor, a former Home Secretary and Barbara Brooke, Baroness Brooke of Ystradfellte. He was elected as Conservative MP for the City of London and Westminster in 1977. He was made Chairman of the Conservative Party in 1987, and was made Secretary of State for Northern Ireland in 1989. He remained in this position until 1992, one of the few ministers to retain the position they had held under Margaret Thatcher under the new leadership of John Major. He caused controversy when he appeared on The Late Late Show the day after an IRA bombing and sang the song Oh My Darling, Clementine.

After the 1992 general election he stood down and became a backbench MP, but later that year became Secretary of State for National Heritage until 1994. He stepped down as an MP at the 2001 general election and entered the House of Lords in October 2001.
