Sir Robin John Maxwell-Hyslop (6 June 1931 – 13 January 2010) was a British Conservative Party politician.
Maxwell-Hyslop was educated at Stowe School and Christ Church, Oxford. He worked for the aero engine division of Rolls-Royce from 1954 to 1960.
He contested the Derby North constituency at the 1959 general election. When the Tiverton MP Derick Heathcoat Amory was elevated to the peerage in 1960, Maxwell-Hyslop was elected as his successor in the resulting by-election, and retained the seat until he retired at the 1992 general election. His successor was Angela Browning. He is particularly remembered for an incident, recorded in Hansard (Commons, 18 October 1973), concerning a visit to the Knesset:
Maxwell-Hyslop was the longest-serving member ever of the Commons Select Committee on Trade and Industry, from 1971 to 1992. (The select committee structure was altered in 1979, with Maxwell-Hyslop continuing to serve on the committee in its new form.) He was also the last Conservative MP to ask Prime Minister Margaret Thatcher a question at PMQ's.
He was knighted in the 1992 New Year Honours.
