Mark Ruwedel (born June 11, 1954) is an American landscape photographer and educator. Ruwedel has written: "I am interested in revealing the narratives contained within the landscape, especially those places where the land reveals itself as being both an agent of change and the field of human endeavour." He has made work depicting evidence of human presence in remote, barren and desert regions of North America, predominantly in black and white. His books include Westward the Course of Empire, depicting the remains of abandoned railway lines in the landscape of the western United States and Canada; and Message from the Exterior, abandoned and decaying houses in desert communities around Los Angeles. Ruwedel was Associate Professor at Concordia University, Montreal from 1984 to 2001 and has been Professor of Art at California State University, Long Beach since 2002. He is based in both California and coastal British Columbia. In 2014 he was awarded both a Guggenheim Fellowship and the Scotiabank Photography Award. In 2018 he was shortlisted for the Deutsche Börse Photography Prize. He has had solo exhibitions at the Chinati Foundation, Presentation House Gallery and Southern Alberta Art Gallery. His work is held in the collections of the J. Paul Getty Museum, Los Angeles County Museum of Art, Metropolitan Museum of Art, Museum of Contemporary Photography, National Gallery of Art, National Gallery of Canada, and San Francisco Museum of Modern Art.
