Hendrik Koekoek (22 May 1912 – 8 February 1987) was a Dutch farmer, politician, and founder of the defunct Farmers' Party (Boerenpartij; BP).
Koekoek was the leader and party chair of the BP from 1958 until 1981. He served as the party's Parliamentary leader in the House of Representatives from 5 June 1963 until 10 June 1981. He was also a member of the States-Provincial of Gelderland between 6 June 1962 and 5 June 1963. Although he was widely known, he was never a major force in the Dutch political landscape.[1]
