Ian Joseph Evans OAM (born Parkes, New South Wales, 1940) is an Australian author, publisher and historian. Evans discovered the use of deliberately concealed objects to protect Australian houses and other buildings from evil spiritual forces in the period 1788-1935. The author of books on the history and conservation of old Australian houses, Evans contributed to the growth of the heritage movement that spread throughout Australia in the 1980s. His first book, Restoring Old Houses (MacMillan, 1979) is credited with having stimulated the movement. Other books followed, including several published by Evans's family publishing house, The Flannel Flower Press Pty Ltd.
