Horace Maybray King, Baron Maybray-King, PC (25 May 1901 – 3 September 1986) was a British politician who served as a Member of Parliament (MP) from 1950 until 1971 before becoming a life peer. For most of his time in Parliament, he sat as a Labour MP. Following the death of Harry Hylton-Foster in September 1965, King, who had served as deputy speaker for ten months, became the Speaker of the House of Commons. As was customary, he renounced his party allegiance upon taking up the post. He was the first person from the Labour Party to hold the post.
