Robert Glenn Ketchum (born December 1, 1947) is pioneering conservation photographer, recognized by Audubon magazine as one of 100 people "who shaped the environmental movement in the 20th century.".

Life and career
Ketchum attended high school at the Webb School of California. He received a B.A. in design from UCLA and a MFA from the California Institute of the Arts in 1974.  He studied photography under the direction of Edmund Teske and Robert Heinecken. After he graduated he began a lifelong friendship with Eliot Porter, who helped form his ideas about photography and about how photography can be used to help change the world. His commitment to conservation photography is unique amongst academically-trained photographers.

Prior to his emergence as a photographer, he was a widely recognized curator, discovering the Paul Outerbridge, Jr.  estate, and bringing recognition to the overlooked work of James Van Der Zee. He was also Curator of Photography for the National Park Foundation for 15 years, and in this capacity authored American Photographers and the National Parks (1981).

After the publication of this last title, Ketchum began to concentrate on environmentally focused projects. Although his conservation photography encompasses many areas from Mexico to Canada, his most influential work was done in Alaska, the location of four books with Aperture. His book The Tongass: Alaska's Vanishing Rain Forest (1987) was instrumental in helping to pass the Tongass Timber Reform Bill of 1990. He subsequently turned his attention to Southwest Alaska with Rivers of Life: Southwest Alaska, The Last Great Salmon Fishery (2001) and  Wood-Tikchik: Alaska¹s Largest State Park (2003), advocating for the protection of Bristol Bay from the industrial invasion of oil and gas leasing and the largest open pit mine in the world. In 2010, the Obama administration withdrew Bristol Bay from oil and gas lease consideration.

Ketchum and his close friend master printer Michael Wilder pioneered Cibachrome color printmaking in the early 1970s. They were also among the first contemporary photographers to explore print scale. Ketchum's very dimensional prints large color prints were distinctive at that time.

Ketchum has extended the traditional media of the photographic prints in several ways. He has been working with a guild of embroiderers in China translating his imagery into wall hangings, table screens and standing, multi-panel floor screens using historic craft dating back from 2500 years. More recently, he created the company RGK THREADS to bring photographic images from the natural world to bolt fabric design.

Ketchum has had over 400 one-man and group shows, and his photographs are in major museum collections throughout the world, including the Museum of Modern Art (New York City), the National Museum of American Art (Washington, D.C.), the Museum of Contemporary Art, Los Angeles, and the Metropolitan Museum of Art (New York City), to name a few.  Significant archives of more than 100 images have been acquired by the Amon Carter Museum in Texas and the Huntington Library in Los Angeles, and substantial bodies of work can be found at the High Museum in Atlanta, the Los Angeles County Museum of Art, the Akron Art Museum, The Cantor Museum of Stanford University and the Herbert F. Johnson Museum of Cornell University.

He is the founder of the Advocacy Arts Foundation, and a founding Fellow of the International League of Conservation Photographers.
