Bradley Garrett (born January 4, 1981) is an American social and cultural geographer at University College Dublin in Ireland and a writer for The Guardian newspaper in the United Kingdom. He describes his research interests as being at the intersections of cultural geography, archaeology and visual methods and writes that his research is about "finding the hidden in the world". He is the author of five books including Bunker: Building for the End Times, a contemporary account of doomsday preppers around the world, and Explore Everything: Place-Hacking the City, an ethnographic account of the activities of the London Consolidation Crew (LCC), a group of urban explorers Garrett calls "place hackers".
