Barry Wayne Haase (born 19 November 1945), Australian politician, was a Liberal member of the Australian House of Representatives from October 1998 to August 2013. He initially represented the Division of Kalgoorlie, the largest parliamentary constituency by area in the world, in Western Australia. In 2010, Kalgoorlie was abolished, and Haase transferred to the newly created Durack, essentially the northern half of his old electorate.
